đź’ˇ A Complete Guide to Installing Underwater LED Boat Lights
If you’re ready to upgrade your boat with lighting that looks incredible and adds real function, underwater LED lights are a smart choice. They boost safety, attract fish, and make your vessel stand out at night. In this guide, we’ll walk you through how to choose, install, and maintain underwater lights—and highlight top picks from DRSA, including new options from Lumishore.
🚤 Why Install Underwater LED Boat Lights?
Before we get into the how-to, let’s look at why these lights are worth it:
-
Better Visibility at Night – Light up the water around your boat when docking, launching, or cruising.
-
A Custom Look – Choose vibrant single-color or full RGBW options to give your boat a high-end glow.
-
Attract Marine Life – Great for night fishing, these lights attract baitfish and predators alike.
-
Boost Resale Value – Underwater lighting gives your boat a modern, upgraded appearance.
At DRSA, we carry a curated selection of IP68-rated underwater LED lights designed to perform in tough saltwater environments—from basic white to full-color spectrum systems.
🔧 How to Install Underwater LED Boat Lights
1. Plan the Placement
Mount lights below the waterline—usually on the transom or hull sides. Make sure they won’t be blocked by ladders, trim tabs, or outboard engines.
2. Choose the Right Fixtures
Look for lights with:
-
IP68 waterproof rating
-
Marine-grade housing (stainless steel or polycarbonate)
-
12V or 24V DC compatibility
-
High lumen output for maximum brightness

3. Drill & Mount
Mark your drill holes carefully. Use marine-grade sealant to secure the fixture and prevent leaks. All lights should sit fully below the waterline.
⚠️ Pro Tip: Lights installed above the waterline may overheat or look underwhelming—always go below the line.
4. Wire the LEDs
Use marine-grade tinned copper wire and connect to your 12V or 24V system. Add a fuse or breaker as needed. Many LED lights now support remote controls or dimming via systems like Poco.
5. Seal & Test
Use heat-shrink tubing and dielectric grease to protect connections. Test everything on land before launching your boat.
🧼 Maintenance Tips
-
Rinse lights with fresh water after saltwater trips.
-
Check regularly for algae, barnacles, or buildup.
-
Use a soft brush and marine-safe cleaner to keep lenses clear and bright.
