Underwater Boat Lights Buying Guide

Adding underwater lighting as a modification to your boat or yacht is an excellent way to make life easier and add value to your boat.

Underwater lights for boats provide light for night time fishing and some anglers believe it attracts fishes to the boat.

The main reason many boat owners choose this type of modification is simply to make their boat more attractive and modern.

The choice of color that the underwater light may be is dependent upon the manufacturer.

Many include multiple colors such as red, blue and green but the most popular is the solid white xenon look.

Many premium lights have modes that can come in the form of strobe lighting and many more.

However, you will expect to pay a premium for this sort of functionality.

Although underwater boat lights are not an essential component of your boat, they are still an excellent investment that adds value to your boat.

To help you make an informed buying decision, we have produced the buying guide below.

Underwater Boat Lights

LED, Xenon or Halogen

LED’s are the most popular form of underwater lighting for boats, this is due to many benefits such as a limited amount of power required, long-lasting bulbs, low heat exposure, and zero lag.

Xenon light is mostly used in the automotive scene but they are seen here and there for underwater lighting.

They provide a strong light penetration and spread but do become hot and prone to reliability issues.

Lastly, the older halogen bulbs are a cheap alternative to all of the light sources above.

However, they are soon becoming extinct due to the fact they draw so much power, provide a poor lifespan, low lumens and become hot after prolonged usage.

Underwater Lighting Installation

Installing the lights so that they work underwater usually requires drilling small holes into the transom of the boat.

This is not something to be worried about as the underwater light will usually come as a kit with all the hardware and mounting gear.

In short, you will need to align the light where you want it to be, drill through the hull, wire into a power source and ensure it is watertight.

An excellent guide to installation can be found at Boating Mag with a 10 step guide.

Housing Materials

As the underwater boat lights are mostly going to be submerged in water, it’s vital the material will not become corroded from the salty water.

This will involve using materials such as bronze, stainless steel, and durable plastic.

Almost all of the mid-range to premium lights will be bronze or stainless steel and they are what looks the best.

When on a budget, the majority will be plastic that won’t have the WOW factor but will do the job just fine.


Underwater lights for boats are a great modification that can be done by the majority of boat owners.

It can make any boat look more modern than it actually is and provides a number of other benefits.

Due to the nature of underwater lighting, prices are not that cheap apart from the TH marine light.
