10 Best Underwater Boat Lights 2025 in the United States

The OceanLED 012307C X-Series X8 is a solid choice if you want vibrant, colorful underwater lighting for your boat. It offers a bright output of 2900 lumens, which is plenty to illuminate underwater areas effectively and create striking visual effects. The RGBW color option means you can enjoy a range of colors plus white light, adding versatility for mood or functional lighting.

The light uses durable plastic with a chemically resistant optical polymer shade, which should hold up well in marine environments. It installs on the transom or hull and runs on a 12-volt corded electric power source, which is typical and reliable for boat setups. The LEDs are well-sealed with IP68 rated protection, meaning the light is fully waterproof and safe for continuous underwater use.

The product dimensions are a bit large compared to some alternatives, and since it’s plastic rather than metal, it might not feel as rugged to some users. This light is well suited for boat owners seeking bright, multi-color underwater lighting with dependable waterproofing and a modern look.

The Lumitec SeaBlaze Mini underwater boat lights offer a strong 700 lumens of bright white light, which is great for small boats like dinghies, skiffs, or fishing vessels. Made in the USA with marine-grade anodized aluminum housing, these lights are designed to handle tough marine conditions and resist corrosion. Their small size and versatile mounting options allow installation either above or below the waterline with a simple 1/2" hole, making them easy to fit on various boat types. These lights work with a wide range of boat electrical systems (12-24 volts DC), adding to their convenience.

The polycarbonate lens is clear and waterproof, ensuring durability and good light output underwater. They come as a pair, which suits dual-side mounting needs. One standout feature is the long 5-year warranty, which is rare in this category and shows the manufacturer's confidence in the product’s quality. With just 12 watts of power, these lights are best suited for smaller boats rather than large vessels needing more intense illumination.

For those with small boats seeking reliable, compact underwater lighting that offers good brightness and build quality, the Lumitec SeaBlaze Mini represents a dependable option.

The Lumitec Lighting 101460 is a strong contender in the underwater-boat-lights category. With a brightness of over 2000 lumens in white, it provides ample lighting for night-time boating or fishing. It offers a full-color spectrum (RGBW), allowing for a variety of lighting colors without the need for external controllers, which is a significant convenience for users. The light is surface mountable, which means it can be installed without the need to drill holes in your boat's hull - a big plus for easy installation and maintaining the integrity of your boat.

Additionally, the light self-isolates from any metallic surfaces with a simple 2-wire hookup, reducing the risk of corrosion or electrical issues. The housing is made of naval grade bronze with heat tempered glass, ensuring durability and longevity even in harsh marine environments. Its power consumption is 25 watts, which may be a consideration if power conservation is a priority on your boat. Being waterproof adds to its suitability for underwater use, but its size (18 x 10 x 6 inches) and weight (1.55 pounds) might require you to ensure you have adequate space and mounting support on your boat.

Available since 2017, it may not feature the latest technology but still remains a reliable choice.
