What is an Underwater Boat Light


It is a light on the transom, under the hull, and outrigger spreader, among other different parts of the boat. The right light will create a brighter environment for a safer boating experience, even for night swimming. It warns other boaters of your presence. It makes it easier to traverse the dark waters. To add, it can light up fish and bait!

Types of Underwater Boat Lights

The best way to categorize the boat lights available is based on the main material and technology in the bulbs:

  • HID (High-Intensity Discharge): HID bulb is the traditional choice for underwater lighting. They are known for their exceptional brightness. Plus, they also generate heat, which is a great way to prevent algae and other problems that can damage the light.
  • LED (Light Emitting Diode): LED bulbs are more efficient. They produce less heat. It generates as much light as HID bulbs but consumes lesser energy. LED also offers customizability, allowing you to change the color of the lights as you desire.

Another good way to differentiate the types of underwater lights is through installation.

  • Wired Lights: The products I mentioned in this buying guide belong to this group. They have wires that connect the bulbs to the power source.
  • Wireless Lights: With wireless underwater boat lights, you don’t need to worry about drilling holes. You can attach them using double-sided tape or marine glue. They are also often battery-powered, which can limit light output.

More so, the types of underwater lighting also vary depending on their mounting options.

  • Surface Mount: For most small boats and sailboats, this is the most popular option. It needs small holes for the screws and running the wire.
  • Flush Mount: It is a bit more complicated since it requires flushing, so the wires should get in on the boat.
  • Drain Plug: As the name implies, it is connected to the drain of the boat. Aside from providing light, releasing the plug will let you drain water in the boat.

Benefits and Drawbacks of Using Underwater Boat Lighting


Need more compelling reasons to install lighting under the boat? Below are some of its most notable benefits:

  • Improve Aesthetics: Lighting your boat is a great way to improve its looks. Whether the lights are red, green, blue, and white, they will make your boat look good in the dark. It will command attention and turn heads even at night.
  • Enhance Safety: Boating at night is risky. Collisions are common, especially when another boat is hard to notice. To improve your visibility, installing lights will help. It is an immediate warning to others that you are there.
  • Attract Bait: If you want bait like shrimps and planktons to surround your boat, bright underwater LED lights are must-haves. As a result, the lights make it easier for fish to gather near your location. Green and white lights work best for this purpose.
  • Improve Water Clarity: A marine-grade light comes in handy when the sun sets and you want to go for a swim. A good light will make it easier to see when you are in the water. Aside from safety, it also allows you to appreciate underwater beauty.

While underwater lighting has plenty of benefits, it can also have several drawbacks, including the following:

  • Need to Drill Holes: In some cases, installing lighting requires drilling holes. The size of the light indicates the number of holes necessary. These holes can cause water to get in the boat if you are not careful with the assembly.
  • Costly: Underwater boat lighting solutions vary in terms of price. A lot of high-quality lights are expensive. Although, as I note in my earlier recommendations, there are also affordable alternatives.

Buyer’s Guide

Finding the right brand and model of underwater boat lighting is not a walk in the park. To narrow down the possibilities, below are the most important details.


The choice of color is important beyond aesthetics. Pick a light color compatible with a specific situation and application. Marine-grade lighting has single or multiple colors. There is a convenient switch or even a mobile app that will let you change the color lights manually.

Red, green, blue, and white are the most popular colors. Red light is for the left or portside, which warns another vessel that a boat is approaching. Green is for the starboard side. White repel bugs and it is great for shallow waters and sandy bottoms. Both green and white are useful for fishing. Blue light, meanwhile, is a relaxing color.


You don’t need to pay for the professional installation of marine-grade boat lighting. It is easy to do on your own, as long as you choose the right product. The best ones are those that do not require a lot of time and effort to install. Choose a light that does not require a lot of drilling. In most cases, a small hole for the mount and screws are all that you will need.


It reflects the lighting output. The most important is the lumen rating. A higher number indicates a brighter light. Smaller lights have smaller lumens. For navigation, at least 600 lumens are necessary. Meanwhile, if you only want to create a dramatic and calming effect, then you can choose a lower rating.

Furthermore, I have a list of the top-rated battery-powered navigation lights and the perfect boat navigation lights for your preference.

Beam Width

This is the angle of view of the lighting. Larger boats require larger lights, especially in darker environments. It ranges from 90 to 120 degrees. Decide if you want the light to be narrow or wide to choose the appropriate beam width. For underwater lights for fishing, you need a wider beam to attract more fish.


To ensure the durability of the boat light, the housing construction is crucial. From marine-grade bronze alloy to aluminum, the materials vary. Most of the products I reviewed above come with stainless steel housing. Rust and corrosion resistance are important to guarantee longevity.

Energy Efficiency

Choose lights with minimal power consumption without compromising performance. With energy-efficient lighting, you won’t be draining the battery too fast. It does not demand a lot from your power system. LED lighting is the best option if efficiency is an important consideration for you.

Number of Bulbs

The light is more powerful the more bulbs are present. High-quality underwater boat lights have anywhere from 10 to 30 bulbs. Meanwhile, small lights will have as few as three bulbs. Consider the dimension of the boat and desired brightness to determine how many bulbs you need.


Choose a marine-grade light with a size congruent to your boat. If you have a small boat, pick a small light. Three to four inches is enough for small boats. For larger boats, on the other hand, I recommend going up to ten inches.

Care and Maintenance

Underwater lights are prone to damages from marine life, including algae and barnacle. Exposure to saltwater also speeds up corrosion, unless the light is made of marine-grade stainless steel, aluminum, or bronze, among other similar materials. To maintain the light’s peak performance, below are the most important things to do.

  • Check the lights regularly for any sign of damage. The earlier you see the problem, the quicker you can react. This prevents the issue from getting worse.
  • Ensure proper installation. Keep the lighting tight and secure, preventing water from getting in.
  • Once the boat is docked, use freshwater, mild soap, and brush to clean the lighting. This will rinse saltwater and other elements that cause long-term damage.
  • Keep the light wires neat. Hide them in the boat. Otherwise, it is prone to damage if it is exposed.
  • Pick the right cleaning materials. Avoid harsh chemicals and abrasives. Use mild soap and a soft towel to prevent scratching the surface.
  • If you are using portable underwater lights for boats, keep them in a safe place after using them. They often come with a storage bag to protect from dust and dirt.

Will an underwater boat light attract fish?

Yes, the right lighting helps to attract fish around your boat. Any light under the water, regardless of its color, will illuminate the area.

Once the baitfish is around, it will attract larger fish, increasing the chances that you will have a fresh catch.
