Partsam 12V Submersible Square LED Trailer Light
The Partsam unit is designed for universal truck and trailer use, including boats and other equipment under 80 inches wide. It features 12 red LED diodes for the stop/turn/tail functions plus a separate license-illumination setup for the driver side, enhancing nighttime visibility. This kit supports multiple functions per side, making it a flexible option for mixed trailer configurations. Best for owners who want a multi-function light with dual-side setups and a DOT-focused design. A noted limitation is the need to confirm compatibility with non-standard vehicle housings before installation.
Wellmax 12V LED Trailer Lights
The Wellmax kit is a low-profile, fully submersible option with two 12V LED tail/turn lights and included stainless hardware. The package emphasizes long-term use with corrosion-resistant materials and an acrylic lens designed to keep water out, while maintaining high visibility. It is fully compliant with DOT FMVSS108 standards, which helps reduce liability concerns in the event of an incident. Better for buyers seeking a ready-to-install, perimeter-ready pair that withstands wet environments. A potential limitation is that it comes as a two-light kit, so larger trailer needs may require additional units.
CZC AUTO 2PCS 12V Submersible Lights
The CZC AUTO pair focuses on under-80 inch width trailers with a 7-function left and right light setup, including license plate illumination. The product prioritizes water resistance through IP68 sealing and sonic welding for a solid waterproof bond. It uses 18-gauge copper wiring to ensure reliable underwater performance and claims full DOT testing alignment. This option is ideal for buyers needing a robust, multi-function kit that remains reliable underwater. A caveat is the potential for complex installation due to multiple functions and wire routing.
MAXXHAUL 70205 Trailer Light Kit
This all-in-one kit provides two 12V LED stop/tail/turn lights, two amber clearance lights, a license plate bracket, and a wiring harness. It emphasizes easy installation with a 22-foot, color-coded harness that helps reduce setup time. The kit is positioned for trailers needing a complete lighting solution in one purchase, including license plate illumination. It’s best for buyers seeking a broad, ready-to-install package with a straightforward wiring path. A limitation is that it may require additional components for very large or uniquely configured trailers.
LINKITOM Submersible LED Kit
The LINKITOM kit is designed for over-80″ trailers with halo-style lighting and a comprehensive wiring package. Its IP68 waterproofing and fully welded construction emphasize long-term submersion performance. The kit includes two halo stop/turn lights, clearance lights, and a wiring harness, plus a license-plate bracket. The design favors buyers who want a visually distinct, bright trailer lighting solution with reliable water resistance. A caution is the drainage guidance; install with the drain hole downward to aid water removal.
Buying Guide
Key decision factors to consider when selecting boat trailer submersible lights:
- Trailer width compatibility: Most kits target under 80 inches; verify your trailer’s width before purchasing.
- Functions required: Some kits include license plate illumination and multiple markers; decide if you need dual-side functions or single-side configurations.
- Water exposure and sealing: Look for IP68 or higher ratings and a fully sealed housing to ensure underwater durability.
- Wiring and installation: Consider the length of the wiring harness and whether a color-coded harness is included for easy installation.
- DOT/FMVSS108 compliance: DOT-compliant lights reduce risk in liability scenarios and improve visibility standards compliance.
- Materials and corrosion resistance: Stainless hardware and corrosion-resistant plastics extend life in salty or humid environments.
- Warranty and inspection: Check for quality inspections and warranties if available, especially for frequent water exposure.
FAQ
- Q: Are submersible trailer lights legal for use on all trailers? A: Many are DOT/FMVSS108 compliant, but always verify local regulations for your specific trailer type and width.
- Q: What does IP68 mean for trailer lights? A: IP68 indicates the lights are dust-tight and can be submerged beyond 1 meter for extended periods under test conditions.
- Q: Do these kits require professional wiring? A: Some kits include color-coded wiring and harnesses designed for DIY installation; complex trailers may benefit from professional help.
- Q: Can I mix brands in a trailer lighting setup? A: Mixing is possible but ensure compatible voltage, wiring, and function schemes to avoid inconsistent signaling.
- Q: Will submersible lights affect trailer electrical systems? A: Properly sealed LED lights with dedicated wiring reduce risk to the vehicle’s electrical system when installed correctly.
- Q: How do I choose between two-light and four-light kits? A: Two-light kits work for standard trailers; four-light kits offer more rear visibility and license illumination on dual-axle setups.
