What Exactly Are Underwater Boat Lights?

If you are new to boating, perhaps you do not know exactly what to think when you hear about underwater boat lights. These lights are placed on the outside of your boat, under the waterline. Most boat owners mount them on the transom.

These items are meant to illuminate the water underneath your vessel making your life so much easier. Moreover, you can choose pretty much any color you like for the light. This way, you will be able to see everything around you and be safer than without them.

Benefits Of Underwater Boat Lights

Best Underwater Boat LightsIn terms of safety, there are a few things your boating gear should contain and underwater lights should be one of them. Let us show you why you should consider getting such items.

1. Increased Visibility and Safety

As the name suggests, if they are lights, they are meant to illuminate. This results in better visibility both for you and for others. You will be safe from any danger that may come your way, and you will be able to avoid it in time.

Also, if you decide to take a swim, the underwater lights will help you see the area you are diving into much better. Moreover, since you are so illuminated, there is no chance for other vessels not to see you whether they need to avoid you or find you, in case of an emergency.

2. Excellent Fishing Experience

If you are an angler, having underwater lights makes fishing a more comfortable experience. Some fishing enthusiasts even state that fish are attracted to lights. Therefore, your catch might be much more prosperous compared to daylight fishing.

3. Your Own Boat Aura

This may not be the most important benefit, but your boat will have its own aura. How cool is that? If you like spending time at night on the open water, you will surely appreciate being surrounded by beautiful color lights.

You will be able to create a more relaxing ambient environment and simply chill, mesmerized by the wonderful surroundings.

4. Peace of Mind

No matter how often you have been out on the water at night, this is a stressful situation. Not being able to properly see what is ahead, and the constant worrying about hitting something can cause a lot of frustration.

However, if you equip your boat with underwater lights, all your worries will disappear, and you will be able to fully enjoy your boating experience. Sailing or fishing on your boat is supposed to be relaxing activities where you can eliminate all the stress and recharge your own batteries. You do not need any more frustration!

5. Cost Efficiency

You should also know that high-end underwater boat lights are investments worthy of every cent. Besides the fact that they can serve you for a really long period, you can even save money because some models are energy-efficient, especially LEDs.

6. Versatility

When it comes to any product category, it is always good to know that you have options. For example, you can get small-sized LED lights that can be installed pretty much anywhere, in any type of design, and still deliver really bright lighting.

Types Of Underwater Boat Lights

Underwater Boat Light ReviewsIf you perform a simple online search on underwater boat lights, most results will give you LED lights. This is the most popular type and most boaters use them. However, there is another type

1. Incandescent Light Bulbs

The intensity of the light you will get is determined by the wattage of the incandescent light bulbs. Equally-heated filaments produce light. If you want the brightness to be higher, you have to increase the wattage.

For this reason, incandescent light bulbs are considered as being part of a generation of wastage of energy and heat. Another reason why energy is lost is the equal creation of light around the lamp. This type of underwater light is cheap and will offer a wonderful warm glow.

However, you need to know that incandescent light bulbs are known for early damage, and they are not really durable. The reason for this is the filament that burns out quite fast and you end up having to replace the bulb.

2. LED Underwater Lights

As previously mentioned, this type of underwater light is more popular with boat owners because they offer a lot more benefits. First of all, they produce a low quantity of heat. For this reason, LEDs burn cooler compared to incandescent bulbs.

Moreover, this type of light has up to 100,000 working hours. Incandescent lights have only around 1,000. LEDs do not have filaments, so this is another reason why they are so durable. They are not as fragile as their counterparts, and they are energy-efficient, which is probably the biggest advantage.

However, there is one disadvantage here, because LEDs are more expensive. Still, they do not emit toxic chemicals such as mercury. Therefore, they are environmentally friendly as well.

Fishing With Underwater Boat Lights

Fishing With Underwater Boat LightsMany anglers believe that light attracts fish. We have not seen a scientifically-proven explanation, but many fishing enthusiasts swear that it works. It seems that night fishing with lights attracts fish such as zooplankton to the surface, as they chase the light source. It appears that zooplankton is attracted to white and green lights.

Using green light is especially useful where water clarity is poor because it makes it appear cleaner and reflects less. You should also know that colors penetrate the water at different lengths. For example, red light cannot be seen past five meters, orange ten, and yellow 20. Green can be seen at lengths of up to 30 meters.

That is why green and white lights are more recommended for fishing at night. Submerged lights can only be used during nighttime, and they cannot compete with sunlight to attract zooplankton. Another thing you should know is that the boat should stay very still because the fish could not gather around the light if the vessel was moving.

For this, you can use two anchors. This way, your boat will not pivot. If you want to have successful fishing experience, it is recommended to use two colored lights. One more important thing you should keep in mind is that the water around your boat needs to be deep enough to hold fish.

The first step of the installation process is deciding where you want to mount the lights. As a general line, it is recommended to be at least six inches below the waterline. Moreover, submerged lights need to be placed on clean, unobstructed, flat surfaces.

Once you find the perfect spot, you will need to cut the templates that come with the lights and then tape them to the hull. Make sure you follow the instructions on the templates. You will need to drill holes into the hull, but make sure there is nothing behind these areas. After you finish, clean these areas with a clean towel.

Through the center hole, you will need to run the wires, and then a bead of sealant around the perimeter of the fixture. Next, from the inside of the boat, you will need to pull the cables carefully and position the fixture on the outside.

Use the screws that come with the fixture, and mount it to the hull. When you get to this point, you should refer to the wiring diagrams in order to wire the lighting system correctly. Also, make sure that the exposed wires are covered with electrical tape in order to prevent corrosion.

Of course, depending on the type of lighting system you select, the installation process may differ. Regardless of the type and model, make sure you follow the manufacturer’s instructions and call for professional help if you need it.

Furthermore, if you remove your vessel from the water, you should also clean the lights using mild detergent, clean, freshwater, and a soft towel. It is important not to use any hard detergent or bristle brushes.

Another thing you should keep in mind is that submerged lights work by being kept cool underwater. Therefore, never run these lights out of the water, or you might get them permanently damaged. If you have to do this for some reason, make sure you never exceed two minutes.

FAQ About Underwater Boat Lights

1. What Color Underwater Is The Best?

There is no “best color” for underwater boat lights. It depends on what your needs and preferences are. Each color’s penetration capability depends on wavelength. A short-wavelength offers a deeper color penetration. Blue light has the shortest wavelength which means that it penetrates deeper.

At the same time, red light has the longest wavelength so it gets absorbed at shallow depths. If you only want to make your boat look cool, you can go for whichever color or color combination you like. If you want to fish at night, you should go for green and white. That is why it is important to know what you need the light for before getting the units.

2. Where Should Underwater Boat Lights Be Installed?

When it comes to the areas where the underwater lights should be mounted in, usually the drain plug, the transom, and the trim tab are preferred by most boat owners. Also, if you are a skillful person, the installation process is not very hard.

You need to consider that for most units, you will have to drill holes for the screws and wiring. Also, you will have to hook up the wires to the power source. Therefore, if you have any doubt, you should not hesitate to call a professional. It is better to spend a few extra bucks for his or her services than to cause much more expensive damage to your boat.

3. How Can I Change the Color if I Am Using a Multicolor Lighting System?

This depends on the product itself. Some models offer the possibility to preset the cross fade at certain intervals. You may also be able to turn the lights off and on using the switch that came with the system to change the color.

However, your product may have other options. Therefore, the right answer lays in the manufacturer’s instructions manual which you should read before you even mount the system on your boat.

4. Can I Use My Underwater Boat Lights Out of the Water?

Even if these lights work out of the water, you should not use them for any other than the intended purpose. Submerged lights are designed in a way that the water allows them to cool down.

If you use them outside their intended environment, there is nothing to cool them down, so the heat will damage them. If you need to check the system out of the water, make sure you never keep the lights on for more than two minutes.

5. What Colors Are Fish Attracted to?

Green and white lights are commonly used to attract fish not only to boats but to docks and piers as well. The reason for this is the two colors’ brightness that can attract fish from greater distances. Blue has a shorter wavelength but it is used mostly for ambient and aesthetic lighting, mostly around resort and restaurant areas.

Wrap Up

Even though they are not mandatory, the best underwater boat lights should not be missing from your vessel, especially if you are often on the open water at night. They represent an extra safety feature both for you and for other boaters around you, and they also look great. In case you are an angler, then these units are a must, especially if you like fishing at night.

If you read our underwater boat light reviews, you will be able to see what some of the most popular models are with boat owners.
