Boat Navigation Lights Rules: Illustrated Beginners Guide

When navigating at night, the lights on other boats are your first clue about the moving dangers around you. And your navigation lights are your first line of safety in avoiding collisions in the dark, and they tell others vessels what you are and what you are doing. The rules sound complex, but with a little understanding you can get the basics for any situation.

So what are the basic navigation light rules? For most small vessels, motoring requires red and green (port and starboard) lights, and a white light visible in all directions around the boat. This is almost always a stern light and a masthead light on sailboats. Boats under sail require port and starboard lights, and a white stern light. Sailboats below sixty-five feet may show a tricolor light at the masthead instead of side and stern lights when sailing.

That's it, in a nutshell. There's a little more to it, as the rules change with different sizes and there are some specifics about angles of display for the colors. Identifying other ships at sea requires more study, but the basics are the same. And it's not much trouble to make sure you've always got the proper lights on your vessel.

On this page:

What are the official colregs rules for your sailboat, what about the uscg (united states coast guard) rules, lighting at anchor, identifying the boats around you.

The International Regulations for the Prevention of Collision at Sea , abbreviated "COLREGS" is very specific about the lights required, their shapes and sizes, and the distance they must be visible. For the smaller boat, the following definitions apply.

• Masthead Light - a white light placed centerline on the boat showing an arc of 225 degrees with 112.5 degrees either side of the front of the vessel.
• Sidelights - A red light on the port side and a green light on the starboard. They must show an arc of 112.5 degrees from centerline of the bow.
• Stern light - A white light on the stern of the boat showing an unbroken arc of 135 degrees from centerline of the vessel.
• All-round light - A light showing in an unbroken arc of 360 degrees.

The good news is you need not measure these angles. Any properly installed USCG or COLREGS approved light which will cover the correct arcs. If you have to replace the original light from your boat, make sure it's with an approved replacement.

Lights When Sailing

The specific rules for a sailboat under sail are in COLREGS Rule 25 and vary slightly with the size of the boat. A sailboat powering is considered a power boat and falls under in Rule 23.

• Under 23 feet (7 meters) - side lights and a stern light, possible. If these lights can not be displayed a light must be kept at hand to help avoid a collision. This can be a bright flashlight.
• Over 23 feet - Side lights visible to one nautical mile and stern light visible for two.
• Vessels under 65 feet may combine both sidelights into a single lantern on the bow.
• May show a tricolor light on the masthead instead of sidelights and a stern light. It's one or the other though, do not show these lights at the same time .
• Masthead light must be visible for three nautical miles, all other lights must have a two nautical mile visibility.
• Side lights must be separated.
• May not show a masthead tricolor light.
• Masthead light must have five nautical mile visibility, all other lights must be visible for two nautical miles.
• Optional masthead lights - any vessel under sail may display a red light over a green light at the masthead with sidelights and stern light. The red over green may NOT be displayed with a masthead tricolor light. It's one set or the other.

Lights When Motoring

For all navigational purposes a sailboat under power is considered a power boat. This includes motor sailing - if the engine is on and providing propulsion you are on a power boat, even if the sails are up . This applies to navigation lighting, sound signals in fog and limited visibility, and rights of way.

Sailboats under 50 meters under power need to show:

• A masthead light
• Stern light

A power-driven vessel under 23 feet (7 meters) that does not exceed seven knots of speed may display an all around white light, though sidelights should be used if available.

The USCG has published its own "Rules of the Road" that are based on the COLREGS. In addition, it has rules for the "Inland Waterways" for rivers, inland lakes and the Great Lakes.

The good news is this has no impact on what you have to do with your own boat.

They mostly relate to lighting changes on towed vessels like barges and tugs. For example, a vessel towing or pushing another vessel in the ocean under COLREGS shows two masthead lights, sidelights and a stern light, whereas in Inland Waterways the towing or pushing vessel displays two yellow towing lights instead of a white stern light.

If you sail on lakes, rivers or the Great Lakes where towed commercial traffic is common you should learn the inland lights, but coastal or ocean sailors will never see these.

When you anchor outside a designated mooring field, you should display an all around white light at the masthead or as high in the boat as practical.

If your boat is large and has a very tall mast, you may wish to display another light closer to the waterline. Boats approaching in the dark may not see a light on a mast sixty or seventy feet in the air when they are close to your boat.

We use a simple garden path light on our stern when we anchor, left in a rod holder or flag socket. It comes on automatically at dusk and is a cheap and easy way to be more visible. There is no specific rule stating you can not display more lights than required, or the nature of any lights beyond the required all around light.

The COLREGS also specify that a round black "daymark" should be displayed in the rigging of any vessel at anchor. Very few small vessels observe this, however it is the correct display for a vessel in an anchorage.

If you tie to a mooring in a marked mooring area you are not required to display anchor lights, but there is no harm in doing so.

The other important reason to know your lights is to figure out what's going on around you at night. The water may be ablaze with white, red, green and other lights at night and they are your first key to avoiding collisions and problems.

All combinations of lights for fishing boats, commercial vessels, and so on are outside this post‘s scope. The odds are small you will encounter a submarine, seaplane or hovercraft at night, but there are regulations regarding specific lighting for each of those vessels!

There are a few fundamentals to help you figure out what that is you see on the horizon, which way it is going, and whether it is a danger to you.

Port Wine is Red

The fundamental rule is that red sidelights will ALWAYS be on the port side of a vessel, and green lights will always be on starboard. However, some vessels can use all around red and green lights for other purposes, though those will be higher than sidelights.

The light‘s on a ship is not important, some large tankers and freighters will have their sidelights far aft and put them on the superstructure for better visibility. It is not safe to assume that sidelights you can see are on the bow of large vessels .

When you can see the color, you know which way the bow is pointing. If it's red, it's pointing more or less to the left and will travel in that direction. A green light shows it is heading more or less to your right.

If you can see the red and green lights at the same time, you are looking directly at the bow of the vessel. When you are far away, this isn‘t as alarming as if you are close crossing. Seeing red and green lights together on a vessel is something you never want to see for long.

Be aware of red and green lights used in combination with other red, green and white lights. These may not be running lights and could have other significance.

Tankers, Freighters and Large Ships

Tankers, freighters and large ships will have side lights, a stern light and a masthead light. In addition, on vessels over 50 meters there will be a second masthead light further aft and higher than the forward light. The masthead light positions are a better tipoff to the bow direction and how far from the bow the sidelights might be. Remember - on a large vessel the sidelights may not be at the bow or even close to it.

USCG Inland Rules allow for a second all-around white light on large vessels on the Great Lakes instead of a second masthead light.

Fishing Boats

Fishing boats engaged in fishing will have more complex light displays. When they aren't fishing, they will show lights like any power vessel, but Rule 26 spells out light combinations that vary by the fishing activity being done. In general:

• Boats which are Trawling but not making headway will display a green all-around light over a white all-around light , and a masthead light aft of these lights. Boats making headway while trawling will show these lights, plus sidelights and a stern light.
• A vessel fishing other than trawling will show a red all-around light over a white all-around light . When making way they will also show sidelights and a stern light.
• If a vessel has gear more than 150 meters away from the boat, it will show a second all around light in the direction of the gear. The best rule is to give fishing boats as wide a berth as you can at night. They're easy to pick out if you check the top light configurations but their course may be difficult to predict.

Towing and Pushing

Towed vessels can be the most dangerous to cross, but they have the most lights to tell you what is happening. Refer to COLREGS or the USCG Rules of the Road Rule 24 for all combinations You can pick a tow/push vessel out with the following lights:

• Two or three masthead lights in a vertical line. Three masthead lights shows a tow over 200 meters. Additional masthead lights may show for larger tow vessels.
• A towing light (yellow light with the same characteristics as a stern light) directly above the stern light.
• The will also have side lights and a stern light.
• The towed vessel will show sidelights and a stern light. Lighting may vary under USCG inland rules, where towing lights may replace stern lights. Learn these differences if this is your regular cruising ground. If you think there is a tow ahead of you, always go well behind the aft most set of lights. Never go between a tow and avoid crossing ahead if possible as it may restrict their maneuverability.

Special Situations

There are several rare situations you may encounter. As a general rule, if there are a lot of lights and you don't understand them look for the sidelights on a moving vessel. If you can find them and figure out the direction it is moving, it makes the vessel easier to avoid. Stay well clear of lights you do not understand if you can avoid them without risk.

Most of these signals are used by larger, commercial vessels and you will not need them.

They use these light combinations with other light combinations. For example a towing vessel may also be restricted in maneuverability, and a vessel constrained by draft will show running lights if moving.

• Not Under Command - two all around red lights in a single line
• Restricted in Ability to Maneuver - red, white then red in a single line
• Constrained by draft - three all around red lights

Ultimate Guide To Marine Navigation Lighting

If you drive a car or even ride a bicycle, you might be well aware of the necessity of lighting systems (though in the second case the word ‘system’ doesn’t quite apply) for the safety of you and the people around you. The thing applies just as well for ships. But since they are much larger than a car, the lighting system or navigation lights on ships is a little bit more complicated as well. Marine navigation lighting is also one of the most critical aspects of nautical studies.

It is mandatory for boats of all sizes to have a navigation system . This is to make sure that the chances of any significant accident are minimized. The United States introduced the system in 1838, and the United Kingdom followed suit. Before being internationally adopted in 1897 suitable guidelines were established by the International Maritime Conference which was established in 1889. Three colors were chosen that were to be used for the light colors. They were red, green and white.  This was based on a set of rules specified by the US and are followed around the world to this date.

This article discusses the different rules and regulations of using navigation lights, their importance, and also some basic marine navigation lighting systems along with their positions and ranges.

Marine Navigational Lights, Rules and Regulations

A standard pattern of marine navigation lighting is followed for the identification of both the vessel as well as the IALA buoyage system at night. If you are required to move from sea to a channel you need to have a list of all the IALA as well as the other fixed navigational lights that are visible on entering the channel. This includes distant lighthouses as well.

If you also make a note of the inland features like the radio and television transmitter masts it will benefit you because they act as good navigational aids due to their height and warning lights.

The helmsman should not be using any bright light source in the cockpit area and should rather take the aid of red lights and very dim white lights in the galley and navigation area. This is because he needs to preserve his night vision so that he can accurately interpret both the buoyage marine navigation lights as well as the boat navigation lights of other vessels.

The nautical almanacs contain the details of each and every visible maritime light signal coming from navigational markers that are both inside and outside the channel.

All the details about any particular light can be found in a published list or on a marine navigational lights chart: its color, period, and in some cases even the elevation and range of the beacon. Use the chart to keep a tag on the lights you are passing by putting a tick mark on the lights that you are about to pass and as the boat sails past, the tick is checked.

You will get two visual clues to figure out how far you are away from a buoy. The light will elevate from the horizon at 0.5 nm and at about 200m, the light will reflect on the surface.

Position of Boat Navigation Lights

Most of the variations that can be found in the different vessels can be read about in most almanacs. At the very basic level, a vessel needs to show a red light to port and green light to starboard. Depending on the size of the vessel, one or more colored or white lights are used as well.

For vessels that are 12 ft in length or shorter, the navigation lights must be visible from a range of one nautical mile and for the ones that are longer than 12 meters the required visibility range is 2 nautical miles.  From 5 degrees above to 5 degrees below the horizontal happens to be the required minimum intensity in a vertical sector.

International Navigation Rules state that the boat navigation lights should be placed above the uppermost continuous deck. In case separate fixtures are used for the red and green sidelights, the masthead or all-round white light is placed as close as possible to the vessel’s fore and aft centerline. The masthead or all-around light needs to be positioned at least 1 m or 3.3 ft above the sidelights.

Following are the basic positions of navigational lights. We will discuss the same in greater detail ahead.

Boat Navigation Light Regulations

Several rules and specifications are related to the type, size, layout, arc, and distance of visibility of boat navigation lights used by all vessel types which are collectively known as the International Regulations for Preventing Collisions at Sea or COLREGs . The navigational lights used are known as ‘COLREG lights and shapes. A boat might be anchored or underway, under sail or power, or fishing or trawling. These various situations can be communicated through multiple combinations of boat navigational lights.

In addition to the primary navigation lights, vessels may also display one or more steaming lights. These lights are very useful for it gives details about the various aspects of the ship like whether it is in the sail or under power, the direction in which it is going and, in some cases, even the size of the vessel. If a ship is engaged in a specific task that might involve certain restrictions, that too can be indicated with some extra boat lights.

Always maintain the lighting system and display the correct navigation light combination to make other vessels in the vicinity aware of your course and state as to whether your vessel is under power or not. If you follow this a considerable amount lowers the chances of a collision. Here is a list that you might use to familiarise yourself with the basics of the lighting system.

• Basic Navigation Light White Light : Small dinghies that are 7m or less in size are required to carry a torch having a white light that can be flashed when needed.
• All-Round White Light: An all-round white light is expected to be displayed by a small boat, up to 7ft long that is under power and can go beyond 7 knots of speed. This light must be visible at an angle of 360 degrees and from two miles away. An all-around white light is also used when the boat or vessel is at anchor but not at a designated anchoring area. This is to make sure that the ship is visible to all the nearby ships to avoid any accidents.
• Stern and Combined Side Lights : A stern light is a white light that is installed at the end of a boat.  A vessel that is over 7 m or 23 ft in length is expected to show red and green sidelights when sailing. Each of these lights needs to cover an arc of 112.5°. The sidelights may be combined in one lantern at the bow when below 25 m or 65 ft. The white stern light can be seen over an arc of 135°. These lights need to be visible from a distance of a mile and need to be placed 39 inches below all white lights for boats of lengths equal to or less than 12 ft.
• Masthead Light : A combination of sidelight and stern light in a tricolor combination may be used sailing yachts of heights 20 m or lower.  A masthead light is required by vessels of lengths between 39.4 ft and 65.6 ft. It is placed in the masthead whose height provides excellent visibility. Still, stern lights and sidelights should be fitted separately in case of or use under power along with steaming light. This kind of light needs to be visible across an angle of 225 degrees and from a minimum distance of 2 miles.
• Separate Lights : The displaying of the tricolor masthead light is not allowed in the case of yachts that are longer than 20 m or 65 ft. Instead, they use them separately. Often on large sailing vessels, these all-around, red over green lights are present. These red and green sidelights need to be visible from a distance of one mile and across an angle of 112.5 degrees.
• Steaming Lights Combined Lights : A combination of the masthead and stern light are used in the case of power crafts that are less than 20 m or 65 ft in length. The arrangement is present at the bow.
• Single Steaming Light : Visible over a 225 degrees arc, a masthead steaming light is used by power-driven vessels that are up to 50 m or 160 ft long. Separate stern lights and sidelights are used in case of a length exceeding 20 m or 65 ft.
• Two Steaming Lights: Power-driven vessels that span over 50 m or 160 ft in length display two masthead steaming lights. The forward light placed lower than the aft light with both of them being visible over an arc of 225° with the sidelights and separate stern light.

The area of the nautical lighting system is a precise business and requires some amount of study and a good deal of responsibility. It is because its application forms a core element in safe marine navigation.

Boat Navigation Lights: Understanding the Basics

Table of Contents

For many boaters, the best way to end a beautiful day on the water is to watch the sun slowly drop below the horizon while it lights up the clouds and sky above. Others feel better heading to the dock before the sun goes down, while there is still plenty of light to illuminate the channel markers and other potential dangers.

Besides understanding boat navigation light rules, it is also important to understand:

• The overall purpose of boat navigation lights
• How to properly use boat navigation lights
• What the different colors (red and green) mean

How do boat navigation lights work?

Boat navigation lights, or “nav lights,” are the colored marker lights visible on either side of the vessel and at the stern . These lights play essential roles in identifying the ship’s length, direction, and purpose!

The colored marker lights and where to find them go as follows:

• The boat’s port side is marked with a red light.
• The starboard side light is green.
• When looking at the boat’s transom or stern, a white light may be visible.

Keep in mind large boats and ships may use other colors, like yellow.

Next time you’re boating at night , say thanks to your navigation lights. They allow you to see other boaters in the dark and help prevent collisions. But there is much more to boat navigation lights than that.

How to use boat navigation lights

Each of the boat’s navigation lights is only visible for so many degrees of a circle to prevent confusion and accurately identify which side is in view.

By noting which colors are visible on another vessel, boaters can identify which direction the other boat is facing or headed. Knowing a boat’s direction can be especially important when crossing paths with another vessel in the dark.

If you walked around a boat at night while the navigation lights were on, the color visible would change depending on where you stood. When looking at the port side of the boat, the red light would be visible from dead ahead of the vessel to just past the center of the port side or through 112.5 degrees of a circle. Walk to the starboard side, and the green light would be visible from the bow to just past the boat’s center, or another 112.5 degrees.

Stand at the back of the boat, and you will see the white light visible for a total of 135 degrees from one side of the vessel to the other. Add up all three, and you’ll get 360 degrees.

Boat navigation light color meanings

If you were on a boat at night and could see nothing but the different colored lights of another vessel ahead of you, you would still know exactly which way that boat was going.

• If you could only see the red light ahead of you, you would know that you are seeing the other vessel’s port side, or it is crossing in front of you from your right to left.
• The opposite is true if you saw the other vessel’s green light . You would be looking at the other vessel’s starboard side or watching the boat pass in front of you from left to right.
• If you see both red and green lights , then the other vessel is coming straight at you if you can see both red and green lights.
• If you can only see the white light and nothing else, you would look directly at the other boat’s stern as it drives away.
• Red and white means the boat is driving away from you, crossing from right to left.
• On the other hand, green and white signal that the vessel is moving away from you, crossing from left to right.

When renting a boat on Boatsetter , make it a habit of checking that navigation lights are working. You should turn on the navigation lights even if the sun is out. It’s the best and safest boating practice.

Boat Lighting – Complete Guide to Navigation Lights

I was sitting in the garage the other day admiring my boat when I noticed the green navigation light on the side of the hull, and it dawned on me that I haven’t had the boat out after sunset yet. It also got me wondering about the different places I’d like to travel this summer and what it would be like to navigate in the dark if I had to.

In addition to the legally required lights, I highly recommend having a marine waterproof spotlight in your boat at all times ( this is the one I prefer, which you can buy on Amazon with tons of good reviews ). The little headlight on a boat is nowhere near bright enough to safely navigate if you get caught on the water at night. Trust me, it can save you thousands in boat repairs and a dangerous situation.

I wanted to make sure that I fully understood everything there was to know about navigation lights, so I did some online research. I’ve put together a complete guide of the information I found online talking about the different navigation lights and what I needed to know about them.

What Are Navigation Lights On a Boat?

Boats require specific lighting configuration when operating between sunset and sunrise, or at times when visibility is restricted such as when it’s raining or foggy. Navigation lights are used to help other boaters see you when visibility is reduced, and it allows you also to see the other boaters to avoid collisions.

Navigation lights are also used to communicate with the other boats sharing the water. For example, the navigation lights can tell another boater, what size your vessel is, and in which direction you are heading. This information can be used by the boat caption to determine what the appropriate course of action would be as you approach each other.

By law, the navigation lights come in specific colors; white, red, and green. Even the arc of the illuminated light, the range of visibility, and the location is all specific to what type of vessel you are operating.

Do not assume that your boat came with the appropriate lighting or equipment from the factory or showroom. It is your responsibility to make sure that your boat has the proper navigation lighting configuration before you head out on the water.

What Type Of Boats Requires Navigation Lights?

Basically, in a nutshell, all boats require navigation lights if you’ll be operating them between sunset and sunrise, or whenever visibility is reduced.

This goes for the following types of vessels:

• Motorized vessels
• Non-motorized vessels
• Sailing vessels (Operating under sails)
• Sailing vessels (Operating under motor power)
• Vessels engaged in fishing
• Vessels engaged in trawling
• Towing vessels
• Anchored vessels
• Human-powered vessels such as Rowboats (Kayaks and canoes)

What Lights Are Required On a Boat?

Boats are required to have navigation lights. Navigation lights are required whenever you are operating your vessel between sunset and sunrise, or during any other times when your visibility is restricted from elements such as fog or rain.

The type of lights required depends on the length of your vessel as well as if it’s a powered or non-powered vessel. But in general, all navigation lighting systems will consist of red and green sidelights, as well as one or more white lights. A red sidelight indicates the port side of the vessel, while a green light shows the starboard side of the vessel. The white light in most cases is called an all-around light, which means it can be seen from any angle by other boaters.

Another type of navigation light is a yellow light. A yellow light is not very common to see, but if you do happen to see one, it would mean that a  lead boat is towing another boat. 

It is your responsibility to make sure you have the proper navigation lighting. It is also recommended that you take spare bulbs with you. The USCG doesn’t care if the lights were working when you left, they only care that the lights are not working when they are required.

Lights Required For Power Vessels Underway:

A powered vessel includes all motorized boats, including sailboats that use a motor.

Vessel length: Under 12 meters (39.4 FT.) Lighting requirement:

• One all-around white light that is visible at 360 degrees, and can be seen from two miles away. The all-around white light must be mounted at least 39 inches above the side lights.
• A pair of red and green sidelights that are visible 112.5 degrees and can be seen at least one mile away.

Vessel length: 12 meters to 20 meters (39.4 FT. to 65.6 FT.)  Lighting requirement:

• A white masthead light located at the front of the boat, pointing in the direction you are traveling. This must be visible at 225 degrees and from two miles away. The masthead light must be positioned at least 8 feet above the gunnel.
• A white stern light located at the rear of the boat that is visible at 135 degrees and can be seen from 2 miles away.

Lights Required For Non-powered Vessels Underway:

A non-powered vessel includes sailing vessels and all other types of vessels that don’t have motors such as paddled, poled, or rowed.

Vessel length: Under 7 meters (23 FT.) Lighting requirement:

• You are required to display a white light that can be seen by other boats. White light could consist of a flashlight, torchlight, or lantern.
• If you can, it is recommended that you have an onboard 360-degree white light all-around set on the horizon, with a distance of at least two miles.

Vessel length: Over 7 meters (23 FT.)  – NEED 3 IMAGES Lighting requirement:

• A pair of red and green sidelights, that are visible 112.5 degrees and can be seen at least one mile away.
• Alternatively, for sailboats of that are over 7 meters in length, they can display what is called a tricolor light A tricolor light can only be used while the vessel is underway using sails alone and never while underway by power. This light should also never be used at the same time that the regular sidelights are on. Either the tricolor light or sidelights can be displayed, but never both.

Lights Required For Vessels At Anchor (Less Than 50 Meters):

This rule applies if you are anchored away from a designated area such as a marina.

Vessel length: 12 meters to 20 meters (39.4 FT. to 65.6 FT.) Lighting requirement:

• White all-around light is required to be used so you are visible to other ships that could be in the area.

Understanding The Difference Between Port And Starboard Lights

While standing on the deck and facing the front of the ship, the left side is called the Port and the right side is called the Starboard. The port is always red , while the starboard is always green .

This information is crucial to understand if you ever find yourself trying to navigate the waters at night or while your visibility is limited. For example, if you are sailing towards another vessel, you will be able to tell if that vessel is heading towards you, or if it is heading away from you based on which side the green and red lights appear to you. 

If you see a red light coming towards you, that would mean the other boat is on your right, which means that boat would have the right of way. If you see a green light from an oncoming vessel than you would know that it’s on your left, which means you have the right of way.

When Should Navigation Lights Be Displayed On a Boat?

Navigation lights are required to be displayed in between sunset and sunrise, and anytime that visibility is restricted. For example, due to fog or rain.

Where Can You Buy Navigation Lights?

As discussed earlier, not all boats automatically come with the proper display of navigation lights. It is your responsibility to ensure that your boat has all of the proper equipment for your safety and the safety of others.

The prices for navigation lights will vary anywhere between $9.00 to $100.00 depending on what style and manufacturer you buy. You could even spend as much as $500.00 on some of the higher-end navigation lightings.  Be sure to shop around and take a look at what is available, to ensure that you are finding the best lights, at the best prices.

The dark, endless sea spreads before you as your boat cuts through the waves. Without warning, a massive vessel appears out of nowhere, bearing down on you. But wait–your navigation lights are shining brightly, indicating your position and presence to the other boaters. As you breathe a sigh of relief, you realize that understanding the importance of boat navigation lights is critical for safe and enjoyable boating experiences.

This guide is all about the maritime navigational lights, which are indispensable in:

• Making sure all vessels are visible in low light conditions and periods of limited visibility.
•  Preventing collisions by indicating one’s position and presence to other vessels.
•  Exhibiting the appropriate signals when engaged in specific activities such as towing or fishing.

International Regulations

The International Regulations for Preventing Collisions at Sea (COLREGS) are an important set of guidelines set by the International Maritime Organization (IMO) in 1972. Most countries have adopted these rules for their navigation lights, so boaters should become familiar with them. COLREG documents describe which types and colors of lights need to be used on a boat, as well as where they must be placed.

Navigational Light Basics

Understanding how to light your vessel is critical for ensuring regulations and safety compliance. Onboard lights provide an illuminating beacon, letting those around you know where you are and what you are doing. Boats must use sidelights, sternlights, and masthead lights to clearly designate their location. If engaging in activities like fishing or towing, special lighting may be necessary to give other vessels a heads-up about your situation.

Sidelights are red and green lamps placed on each side of a boat. The red light is displayed on the port (left), while the green one is shown on the starboard (right). This color combination is widely accepted across the world and makes it easy for other boaters to see your direction. Sidelights must be seen from a minimum distance of one mile away in dark, clear conditions.

A brilliant beam of light, stark and white, illuminates the backside of a boat, known as a sternlight. It should always shine bright enough to be visible up to two miles away in clear weather at night. If you’re boating and come up behind another vessel that has its sternlight on, it’s simple to identify which direction it’s headed in. This easy identification is crucial for remaining safe out on the water.

Masthead Light

A masthead light is a white beacon on the bow of ships, boats, and other water vessels that shows which way they are facing. Its purpose is to ensure they are visible from a distance of at least three miles away in dark, clear conditions. Most powerboats are required to have a masthead light, but regulations may differ depending on the size and type of vessel.

Special Boat Navigation Lights

Navigating the open waters can be a tricky business, and that’s why vessels must follow certain regulations to carefully signal their intentions. Here are additional lights for specific vessels:

• Towing Vessels – Boats either pulling or being pulled must show yellow lights in accordance with standard protocol, to ensure other navigators distinguish them from other boats’ lights.
• Fishing Boats – Red and white lamps should be displayed by water vessels partaking in fishing activities, to help prevent accidents between this type of vessel and others.
• Sailboats – A combination of red and green sidelights should be used along with a white aft light on sailing vessels.

Navigation Lights Maintenance and Inspection

It’s essential to stay on top of maintenance and inspection for your boat navigation lights. Follow this guideline:

• Ensure lights are sparkling clean, undamaged, and functioning well by regularly inspecting them.
• Test your navigational lights before heading out on a voyage–especially if you plan to be cruising during periods of low visibility.
• To keep yourself prepared in case of any breakdowns or damages, always bring spare bulbs along with you.
• Upgrade to energy-efficient LED navigation lights for extended lifespans and efficient power consumption.

Familiarize yourself with the navigation lights guide on your specific vessel and maintain it meticulously–and you’ll be sure to experience safe boating with excellent visibility!

Understanding Boat Navigation Lights

Boat navigation lights are essential when you’re out on the water. They’re essential, but it’s easy to misunderstand their uses and correct placements.

If you don’t know the correct placement for your stern lights or know what type of navigation light you need on your mast, don’t worry: we’re here to help. Below, we’ve got an overview of everything you need to know about boat navigation lights: what type of navigation lights you need, where to put them, and why you need to use them.

So without further ado, let’s learn more about boat navigation lights.

What navigation lights are required on a boat?

The U.S. Coast Guard Navigation Rules, International-Inland encompasses lighting requirements for every description of watercraft. The information provided there is intended for powerboats and sailing vessels less than 20 meters. The various options are illustrated.

The U.S. Inland Rules apply inside the demarcation lines at the entrances to inlets, bays, rivers, etc. The demarcation lines are shown on coastal charts as magenta dashed lines. Once outside of the demarcation lines, International Rules apply.

Powered Vessels

Power boats less than 20 meters shall exhibit navigation lights as shown in Figure 1. (Note: 2 masthead lights are optional for vessels under 50 meters. Vessels over 50 meters will display two masthead lights.)

Vessels of less than 12 meters in length, may show the lights in either Figure 1 or Figure 2.

Powerboats less than 7 meters whose maximum speed cannot exceed 7 knots may exhibit an all-round white light, and if practicable sidelights instead of the lights prescribed above, in international waters only.

Sailing Vessels and Vessels Under Oars

Sailing vessels less than 20 meters may exhibit the navigation lights shown in Figures 3 or 4.

Another option for sailboats is to use a single combination lamp at the top of the mast as shown in Figure 5.

Sailing vessels less than 7 meters may carry an electric torch or lit lantern showing a white light to be displayed in time to prevent collision (see Figure 6 – left picture).

If possible, the lights prescribed for sailing vessels less than 20 meters should be displayed.

Vessels under oars may display the lights prescribed for sailing vessels, but if not, must have ready at hand an electric torch or lighted lantern showing a white light to be displayed in time to prevent collision (see Figure 6 – right picture).

Small boats can benefit from using a temporary LED light with a suction cup attachment if permanent fixings aren’t possible.

Shapes and Lights

To alert other vessels of conditions that may be hazardous, there are requirements to display lights at night and shapes during the day.

Anchored Vessels

Powered vessels and sailing vessels at anchor must display anchor lights. An anchor light for a boat less than 50 meters in length is an all-around white light visible for 2 miles exhibited where it can best be seen (see Figure 7).

Vessels at anchor shall exhibit forward where best seen, a ball shape (see Figure 8).

Vessels less than 7 meters are not required to display anchor lights or day shapes unless anchored in or near a narrow channel, fairway or anchorage, or where other vessels normally navigate.

Anchor lights are not required on vessels less than 20 meters, anchored in special anchorages in inland waters designated by the Secretary of Transportation.

Sailing Vessels Under Power

Vessels under sail also being propelled by machinery, must exhibit forward where best seen, a conical shape with the apex pointing down (see Figure 9).

Vessels less than 12 meters are not required to exhibit the dayshape in inland waters.

Sailing vessels operating under machinery, or under sail and machinery are considered as powered boats and must display the lights prescribed for a power-driven vessel.

Restricted Maneuverability

The Navigation Rules require vessels restricted in their ability to maneuver to display appropriate day shapes or lights. To meet this requirement, recreational vessels engaged in diving activities may exhibit a rigid replica of the international code flag “A” not less than one meter in height or at night display the navigation lights shown in Figure 10.

This requirement does not affect the use of a red and white divers flag which may be required by state or local law to mark a diver’s location. The “A” flag is a navigation signal indicating the vessel’s restricted maneuverability and does not pertain to the diver.

Navigation lights should be checked prior to departing the dock and you should always carry spare bulbs. The USCG doesn’t care if they were working when you left, only that they are working when required.

Where do navigation lights go on a boat?

The current navigation light requirements are found in the Navigation Rules, International-Inland, and in Parts 81, 84, and 89 of Title 33, Code of Federal Regulations . They’re easy to find, but many sailors and boat manufacturers do not have a good understanding of the rules governing the proper installation of navigation lights. To help clear up any misunderstandings here’s all you need to know:

Sidelights that are installed in the contour of the bow without providing a mounting surface tooled to be parallel with the fore and aft centreline of the boat are not in compliance with the Inland or International Navigation Rules. Depending on the breadth of the boat near the bow and how far aft from the vessel’s stem the lights are mounted, this shift can be more than 20 degrees in some cases. Installing the fixtures too far aft of the vessel’s stem may result in the sidelights not being visible from a position dead ahead.

Another factor in the proper installation of sidelights is that they must maintain their required minimum intensity in a vertical sector from 5 degrees above to 5 degrees below the horizontal. They must also maintain at least 60 percent of their minimum required intensity from 7.5 degrees above to 7.5 degrees below the horizontal. Installing flush-mounted sidelights, designed to be mounted to a vertical surface in the hull contour, without providing a mounting surface tooled to be vertical, shifts the vertical coverage sector. This also results in non-compliance with the Inland or International Navigation Rules.

Additionally, most of these flush-mounted sidelights are installed below the vessel’s rub rail. International Navigation Rules require that sidelights be installed above the uppermost continuous deck. Therefore, this configuration would not be in compliance with International Navigation Rules.

When separate red and green sidelight fixtures are used, the masthead light or all-round white light, whichever configuration is installed, must be located as close as practical to the vessel’s fore and aft centerline. For vessels less than 12 meters in length, the masthead light or round lights may be displaced from the fore and aft centerline providing that the sidelights are contained within a common fixture and mounted on the vessel’s fore and aft centerline. The masthead or round lights must be installed at least one meter (3.3 ft.) above the sidelights.

Which navigation lights are you required to display when anchoring your boat for the night?

Boating at night (or in reduced visibility) can present some special challenges. Not only is your depth perception lessened, but bright lights on the shore can also cast misleading reflections on the water and if you wear glasses, or worse yet bifocals, you simply don’t see as well at night as you do during the day.

It is not only important that you be able to identify other vessels operating in your proximity, it is equally important that other vessels see you. Most recreational vessels are less than 30 feet in length and, according to the Rules of the Road, shall be equipped with navigation lights.

These lights not only have a certain arc through which they can be seen but must be seen from a minimum distance. The following lighting requirements are for recreational vessels less than 12 meters in length. (approximately 39.4′)

The arc of the lights and color allows you to determine the direction a boat is moving. How good are your boat’s lights? You should test them to check your nighttime visibility, or you might land yourself in hot water with the Coast Guard.

Whether on a trailer or at the marina, switch on your lights and see how well they can be seen. Walk away from the boat or row away, if you are at anchor or at a mooring, and see how visible the lights are as you move further away. How easy are they to see against the background of lights onshore?

Does your stern light shine dead astern over the required 135º arc or does it shine to one side or up or down? Can it be seen from the required 2 miles and why is that important? As an example, let’s say that your stern lights can only be seen for 1/2 mile. You are underway at 8 knots and a large ship is approaching at 15 knots. The ship is only 4 minutes away from a collision with you. By the time the ship “might” see you, identify the light, and decide on how to move, it is too late. A ship traveling at 15 knots may take miles to stop.

Look at the stern lights again, as you move from the stern toward the bow, does the stern light “disappear” as the sidelight “appears”? The stern light should disappear and sidelight appear at 22.5º abaft the beam. If you don’t see the green starboard sidelight or the red port side light when the stern light disappears there is a problem with the arc of one or all these lights. This means that if another boat were approaching you at the angle where no lights are seen there is an increased risk of collision.

If both the stern lights and side lights are seen brightly at the same time you still have a problem. A boat approaching won’t know whether they are overtaking or crossing and whether they should give-way or stand-on.

You should also check to make sure that your masthead light disappears at the same time each side lights disappear and they both disappear when the stern light appears.

Check your sidelights from dead ahead. You should see both red and green. However, by moving toward one side just 1-3º you should then see only one light. If you still see two lights, an approaching boat won’t be able to tell which direction you’re are going.

It is very important to be seen from a distance but also for an approaching boat to be able to determine your direction of travel.

When boating at night remember the following: “When two lights you see ahead, turn your helm and show your red”.

Thanks for writing this post. I can either place them on the exterior or interior for decorations. Placing them on the exterior side is helpful when I go fishing and indulging in other night activities in the water.

Dalton Bourne on July 26, 2022

We love the lights! We put lights from Seaponer on my Jon boat right above the water line and use them for night fishing! The amount of brightness it offers is an assurance of my boat’s being seen clearly during the night. At the same time, the LED lights don’t consume too much energy, leading to a life span of up to 50,000 hours.

Marine Navigation Lights: The Complete Guide

Navigating the open waters can be a thrilling experience, but it is also a responsibility that requires preparation and knowledge. A crucial aspect of safe boating is the use of navigation lights, which are lights placed on boats to help other boats and vessels identify the boat’s position, heading, and intent. In this article, we will provide a complete guide to marine navigation lights, including the different types, requirements, and regulations.

Every State Has Different Boating Laws & Regulations

While some of these laws are universal across the states, many of them vary by location. Before heading out onto the water, make sure that you do research for your specific area and understand what is permissible in regard to safety guidelines or even local limits on fishing. Knowing the local regulations can not only make your trip go more smoothly but can also help keep you and your fellow water-goers safe.

Types of Navigation Lights

Masthead Light : This is a white light with a 225-degree arc, placed at the highest point of the boat. This serves as the primary light for other boats to identify your vessel’s position. The masthead light is a white light that must be visible for at least 2 miles.

Stern Ligh t: This white light is placed at the stern (rear) of the boat with an arc of 135 degrees and serves to indicate the boat’s direction of travel. The stern light is a white light that must be visible for at least 2 miles.

Starboard Lights : A green light, with an arc of 112.5 degrees should be displayed on the starboard side of your boat.

Anchor Light : The anchor light is a white light that is used when a boat is anchored. This light must be visible from a distance of 2 miles.

Port Side Light : A red light, with an arc of 112.5 degrees should be displayed on the port side of your vessel any time there is minimal light or visibility.

Towing Light : This light is used by boats that are towing another vessel. The towing light is a yellow light that must be visible from a distance of 2 miles.

What is the arc of visibility in lights?

This degree measures how far a light’s ray can be seen from the side or from behind during dark hours. They are usually required 30 minutes prior to the sunsetting.

Regulations and Requirements

The International Regulations for Preventing Collisions at Sea (COLREGs) dictate the use and specifications of navigation lights for boats. The COLREGs specify that boats must display the proper lights during hours of darkness and in conditions of reduced visibility, such as fog. Boats must also have a backup lighting system in case the primary system fails.

It is important to note that different types of boats have different requirements for navigation lights. For example, a sailboat under sail must display different lights than a powerboat. It is the responsibility of the boat owner to ensure that their vessel is equipped with the proper lights and that they are in compliance with the regulations.

Maintenance and Replacement

Regular maintenance of navigation lights is essential to ensure that they are in proper working order. This includes checking the batteries, bulbs, and wiring, as well as ensuring that the lights are securely mounted and not obstructed.

It is recommended that navigation lights be replaced every two years or as needed. When replacing lights, it is important to use lights that meet the COLREGs specifications and are approved for use on boats.

Additional Boat Safety Information

In addition to the navigation lights, there are other safety measures that boat owners should take to ensure a safe boating experience.

These measures include having properly working equipment, such as life jackets, fire extinguishers, and communication devices, as well as being prepared for emergencies.

It is important for boat owners to understand the rules of the water and to always follow them. For example, boat operators should be aware of the right-of-way rules, which dictate which vessel has the responsibility to avoid a collision. Boat owners should familiarize themselves with the signs and markers used on the water, such as buoys and channel markers, which indicate the location of navigational hazards and indicate the recommended course for boats to follow.

Boat owners should also be prepared for sudden changes in weather and water conditions. This includes having appropriate clothing and gear for the conditions, as well as monitoring the weather and water conditions and being prepared to take action if conditions change.

Lastly, it is important for boat owners to educate themselves and their passengers about boating safety. This includes taking a boating safety course, which can provide information about the rules of the water, the use of navigation lights and equipment, and emergency procedures.

Enjoy Boating Safely

Marine navigation lights play a critical role in safe boating by helping other boats and vessels identify a boat’s position, heading, and intent. It is important for boat owners to be knowledgeable about the different types of navigation lights, the regulations and requirements, and the importance of regular maintenance. By following these guidelines, boat owners can ensure a safe and enjoyable experience on the open waters.

Boat Navigation Light Rules and Requirements

Boat navigation lights are one of the most important pieces of safety equipment on your boat, along with personal flotation devices , boat fire extinguishers and boat ventilation systems .

As a boat owner or operator, you are legally responsible for using the correct safety equipment at all times. This is your responsibility whether your boat is moving through the water or you are at anchor, day and night, in all types of weather.

Did you know that boat manufacturers, importers and dealers are not responsible for equipping your boat with legally acceptable navigation lights ? Before you take to the water, check that your navigation lights are:

• the right size and type for your boat and chosen water activity
• the right color and intensity
• attached to the correct parts of your boat
• fully operational.

It’s important to learn all you can about navigation lights for safe, legal boating! Keep reading to find out which lights to use when.

What are navigation lights for?

Navigation lights allow you to see and identify other vessels, and allow other boats to see and identify you. There is not one simple way to use navigation lights; the way they are set up on your boat will indicate the size, activity, and direction of travel of your vessel, so that you and other boat operators can make good decisions and avoid collisions.

By understanding what navigation lights mean, you will be able to safely and legally navigate shared waters under a variety of circumstances.

Boat navigation light requirements

Paddleboats, rowboats and small sailboats generally do not need to display navigation lights, but most other boats are legally required to use some or all of the following:

• A green light to indicate the starboard (starboard sidelight) attached near the bow on the starboard side
• A red light to indicate the port (port sidelight) attached near the bow on the port side
• One or more white lights (stern light and masthead light)
• Other navigation lights , such as blue flashing lights for law enforcement vessels engaged in search-and-rescue (SAR) operations, or yellow lights for vessels that are towing or being towed

Each type of navigation light also has a defined arc of illumination and range of visibility. Angles of visibility must be met when the boat is underway, which means that if your boat rides at a significant bow-up angle, you may need to adjust your navigation lights to compensate.

You must always use navigation lights between sunset and sunrise or in reduced visibility, but there are some exceptions during clear, daytime boating.

Note: It is also important to keep a flashlight on board as a temporary replacement, in case a navigation light burns out.

Boat navigation lights while underway

While your boat is underway, you are legally responsible for displaying the right type of navigation lights. Choosing the right lights depends on several factors, including:

• Whether your boat is powered by an engine (in full or in part)
• The size of your boat , measured in length
• Your boat’s speed
• Where you are boating (inland, international water, etc.)
• Whether you are at anchor.

Remember that your navigation lights must be visible and easily identifiable as such. Other lights on your boat cannot be mistaken for navigation lights, or get in the way of your navigation lights

Sailboat navigation lights

If you are operating a sailboat or nonpowered boat such as a canoe, kayak or rowboat, you still need to use the correct configuration of navigation lights for your boat size and boating circumstances. For comprehensive detailed instructions on navigation lights please refer to the USCG resource. The following are general guidelines:

Sailboats or vessels using paddles or oars, under 23 feet in length:

• One white navigation light (or lantern or flashlight) that is visible from 2 nautical miles away between sunset and sunrise or during periods of low visibility. In the presence of another vessel, the light must be displayed in time to avoid a collision.

Sailboats between 23 and 65.6 feet:

• One white stern light visible at 135 degrees and from 2 nautical miles
• One green starboard and one red port sidelight, visible across 112.5 degrees from one nautical mile away
• A tricolour light, which is a single all-around light which includes the three coloured of lights indicated above, facing the same directions, visible from a distance of 2 nautical miles. This type of light can only be used when under sail, and never when using a motor regardless of whether the sails are hoisted. It may not be used at the same time as regular sidelights.

Powered boat navigation lights

If you are operating a boat with an engine (including sailboats with motors), between sunset and sunrise or under conditions of restricted visibility, you need navigation lights.

Powered boats under 39.4 feet:

• One all-around white light, visible from all directions (360 degrees) from two nautical miles away. This light must be attached at least 39 inches above the sidelights.

Recreational powered boats between 40 feet and 164 feet:

This size of boat requires two white lights which, combined, make up 360 degrees of visibility:

• A white masthead light at the bow, visible across 225 degrees, from 2 nautical  miles away. This light must be attached at least 8 feet above the gunnel.
• A white stern light at the stern, visible across 135 degrees and from 2 nautical miles away.

In addition to:

• One green starboard and one red port sidelight, visible across 112.5 degrees from one nautical mile away.

Boat navigation lights at anchor

When your boat is anchored at a dock, it is not necessary to turn on your navigation lights. However, if you are at anchor in an undesignated area, you need to make other boats aware that you are not moving by displaying an all-around white light where it will be easily visible to any other boats in the area.

Diving lights

If you are boating in a resort area or anywhere there are sunken wrecks or coral reefs, keep in mind that there could be diving activity. Keep your distance and stay alert to the possible presence of divers underwater.

Boats that are accompanying divers must display:

• Three vertical masthead lights in a red-white sequence.

Interpreting boat navigation lights

Installing and using the right navigation lights on your boat is very important, but to navigate safely, you also need to be able to interpret the navigation lights on other boats.

Remember, you may not always be boating under ideal circumstances. Make sure you learn to understand navigation lights and the United States Coast Guard rules of navigation , also called the Rules of the Road , thoroughly, so that you can make good decisions quickly, as needed.

Do you see a green light over a white light? This indicates a fishing vessel that is actively trawling. It may be necessary to avoid not only the boat, but also a large net.

Do you see a red light to the left, with two white lights to the right? Understand that you must yield to the other boat.

There are many other configurations you need to be familiar with to operate your boat safely.

Avoiding collisions

Remember, navigation lights are only a tool. You must also maintain a proper look-out at all times, by sight and hearing, to responsibly avoid collisions. Skippers must drive at an appropriate speed so that you can take effective action to avoid colliding with another vessel or body under or on the water.

Factors like visibility, traffic density, the maneuverability of your vessel, the presence of other lights from shore or scattered boat lights, the state of the sea and the draft in relation to the available depth of water must always be taken into consideration. Radar equipment may also pose certain limitations or offer certain benefits to navigating safely.

It is the boat operator’s responsibility to do everything in their power to avoid a collision, including but not limited to the correct display of navigation lights.

Chapter 2: Boating Safety

Navigation light requirements.

Navigation lights are generally mandatory during times of limited visibility regardless of the type of vessel. These lights are invaluable because they allow boaters to identify the type of vessels around them, as well as their relative size. While learning the different arrangements which apply to different vessels, pay close attention to the differences between the navigation light requirements for unpowered and powered vessels.

Navigation Lights for Unpowered Vessels:

If a sailboat is over 23 feet (7 meters), the following standards must be met:

Unpowered boats of this size also have the option of using an all-around light set up, which is also referred to as a tricolor light.

Vessels over 23 feet (7 meters) but under 65.62 feet (20 meters) also have the option of using a combined red over green configuration mast light.

If a sailboat is under 23 feet (7 meters), the following standards must be met:

Navigation Lights for Powered Vessels:

If a powerboat is Greater than 39.4 feet (12 meters), but less than 65.6 feet (20 meters), the following standards must be met:

Additionally, the masthead must be placed at least 8 feet above the gunnel. Refer to Figure D as an example of the proper configuration. These rules also apply to sailboats using a motor.

If a powerboat is less than 39.4 feet (12 meters), the following standards must be met:

Similarly, powered vessels under 7 meters, with speeds under 7 knots, may feature a white all-around light that is visible from two miles away and, if possible, a pair of red and green sidelights in international waters only.

Additionally, the all-around white light must be positioned at least 39 inches above the sidelights. Refer to Figure A as an example of the proper configuration. Note that sailboat in Figure E is using a motor. Even if a sailboat is flying its sail it may still be under engine power, in which case, it is treated as a powered vessel. Therefore, it is vital to note the configuration of a vessel's navigation lights, and what they communicate about the vessel.

If a vessel is at anchor, the following standards must be met:

This covers the sizes of boats typically operated as a recreational boat. For larger vessels, refer to the U.S. Coast Guard Navigational Rules and Regulations Handbook.

Boat Navigation Lights: Safety with the flick of a switch

When visibility on the water is low, ensure that you have the right marine navigation lights installed from Wholesale Marine. From yachts, to cruisers, small boats, PWC's or even kayaks we offer a variety of portable navigation lights.

Boat stern lights offer a bright white light for visibility on the water. Stern lights come in a variety of mounting options, the two most common are a mounted fixed light or a drop in light on a pole. Boat side lights come in a starboard side (green) and port side (red) light. You can mount a separate light on either side or use a bi-color light that contains both. If your vessel meets the requirements you can always use a tri-color light that combines both stern and side lights.

The size of your vessel determines the United State Coast Guard navigation light requirements you must meet. The requirements are for either a main masthead or sternlight head with a pair of side lights. The lights are required to meet a certain nautical distance shine from dead ahead.

Boats that are less than 39.4’ (12 meters) require sidelights with visibility up to 1 nautical miles and a white stern light up to 2 nautical miles.

Boats that are less than 65.7’ (20 meters) require sidelights with visibility up to 2 nautical miles and a masthead light up to 3 nautical miles.

Boats over 65.7' and less than 164' (20 meters - 50 meters) require sidelights with visibility up to 2 nautical miles and a masthead light up to 5 nautical miles.

Whether you’re searching for bow lights or side lights, Wholesale Marine stocks trusted marine brands including Attwood ,  Perko Marine , and  Innovative Lighting . Find reliable boat navigation lights for every type of water vessel.

Marine Navigation Lights That Meet Requirements

Whether you’re piloting a small fishing boat or large power boat, trust that Wholesale Marine has the right boat navigation lights for you. As you are equipping your boat, it is important to be mindful of navigation light requirements for your style of boat. Power driven vessels are required to have a stern light , and either a pair of side lights or a bow light.

Perko Marine side lights such as the  Perko Vertical Mount Side Light are equipped with a red and green marine navigation lights. Gold plated contacts provide excellent conductivity while holding up against normal wear.

Depending on your application, you may opt-out of boat side lights in favor of a bi-color deck light. Bi-color deck lights like the Attwood Bi-Color Boat Navigation Light , function the same as a side light, but features red and green lights contained in a single unit. This bi-color dual side light offers a universal fit, sitting on a 14” straight 2-pin locking collar pole.

Increase your visibility on the water with the  Attwood LED All-Round Boat Stern Light . This boat stern light offers bright white light and is designed for 360° visibility on boats up to 39.4' in length. This marine navigation light is one of many that we stock that is US Coast Guard Approved for 2 nautical miles.

When your boat is anchored you are required to use a 360° anchor light that is visible up to 2 nautical miles. A perfect choice is the Attwood LED Anchor light . Constructed from enhanced 316 stainless steel and corrosion resistant alloys, this navigation light is designed to hold up. The powerful LED’s are rated for over 50,000 hours of use and produce a light bright enough to be seen up to 3 nautical miles away.

What to Expect from LED Boat Navigation Lights

To simplify your selection process when looking for LED lighting fixtures to accessorize, you will need to research a variety of factors based on your needs. If you wish to upgrade or replace your boat navigation lights here are some key factors to consider.

Lighting Capability

LED lights have evolved to meet diverse lighting needs with some producing clear white light and others providing brightness from any direction. Lumens is the term used to describe the amount of light generated by a particular brand of LED lights.

Angle of the Lights

To avoid eye damage it is crucial to factor in the beam angle when purchasing LED boat lights. Read reviews from past customers to gauge the intensity of the light directed at you or from an angle. Strong LED lighting fixtures can harm your eyes so be cautious.

Energy Efficiency

Comparing the percentage of energy needed to produce sufficient light is crucial when selecting lighting fixtures such as LED lights. Higher lumens per watt make LED lights more cost-effective in terms of energy consumption.

Red Light Output

Excessive heat generation in boat LED lights is a significant concern for buyers. To ensure optimal lighting quality it is crucial to consider the heat output of the chosen LED light.

Ease of Installation

Multiple installation techniques for navigation lights cater to different boating needs but mount components should be ensured for both wired and battery-operated choices. Mounting options range from screws to armbands.

Wired lights are recommended for safety while small boats can benefit from the versatility of battery-operated LED lights. The chosen installation method impacts functionality, service life, and safety, ultimately safeguarding lives and property.

LED light prices will vary depending on select features such as materials used and the manufacturer's design availability. Choosing a manufacturer depends on the buyer's budget and preferences for the intended use of the boating adventure.

Customized features and extended warranty may result in higher prices. To obtain the finest LED light bargain you should scrutinize LED boat lighting warranties that typically span from one to seven years. Do not settle for one that is the cheapest option since it might not suit your intended use or last as long as you may hope.

Quality Materials

To ensure the longevity of LED lights it is crucial for prospective buyers to consider the material used. If the material is prone to rust then the light will eventually corrode.

Always check the manufacturer's material-composition and avoid products made primarily of alloy coating. You should for opt for a top-grade metal or alloy material from a reputable LED light brand.

Your lighting source must be tightly sealed and capable of withstanding harsh weather and moisture. When using LED lights for marine and saltwater expeditions, verify the IP rating.

Look for an IP67 rated LED product. This means it confirms its ability to endure any weather conditions and even some underwater submersion.

Why You Need LED Boat Navigation Lights

LED navigation lights offer numerous benefits. They primarily are designed to allow safe transport on the waterways so that other boats can see you.

Choose quality LED lights for greater energy efficiency and significant cost savings compared to incandescent bulbs. LED lights have diverse uses on land and sea, being useful for lighting homes, businesses, and buildings.

Marine LED cabin lights have become popular as decorative lighting inside homes, while others use LEDs for entertainment, transportation, spotlighting, or reading. LEDs are considered essential lighting tools in any setting.

Other reasons to have efficient ones include:

• Easy installation and durable marine-grade construction
• Versatile performance options based on different brands
• Improved visibility for boat status and navigation
• Helps prevent accidents caused by extreme weather and reduced visibility
• Retain compliance with wildlife and marine laws
• Multiple usage options in other marine applications

Differences in LED Boat Navigation Lights

The boat light packaging is compact upon delivery and LED lights operate similarly to incandescent bulbs. They are initially designed for lighting boats but a lot of these lights now serve multiple purposes and come in various types.

• Navigation: Are essential for indicating the position and direction of sea vessels. Usually with red and green lights in addition to white.
• Anchor: The anchor light serves to locate and signal the presence of a docked vessel
• White: Provides adequate lighting all around the boat
• Deck: These lights offer lighting in areas that you walk through often
• Dock: Serve as bright illumination for boaters or mariners during departure or arrival at a marina
• Underwater: These are submerged or placed near water to lure sea creatures during nighttime fishing expeditions.
• Search: Search lights are essential for boat users to locate objects on deck or in water.

Which Colors Do You Need for Your Boat?

Boat navigation lights consist of red sidelight for port side and green sidelight for starboard side. White lights serve as anchor, masthead, or stern lights.

If you cannot remember how to tell the two apart you can always think of port red wine. There is a saying that you can easily remember such as “there is no red port wine left”. This way you do not have to worry about the starboard side since it works itself out in the phrase if you can remember the port side.

Navigation lights are unnecessary for illumination during normal boat motion except in low visibility conditions. If you decide to use other lights on your boat make sure that they are not in use during lower light conditions so that other boaters are not confused by your setup.
