Buying Guide
Key considerations when choosing a boat trailer light kit:
- Waterproofing and submersibility: Look for IP68 ratings and fully welded housings to withstand frequent submersion and exposure to saltwater and mud.
- DOT/FMVSS108 compliance: Ensure the kit meets safety standards for trailer lighting in the United States.
- Wiring harness length and color coding: Verify that the included wiring harness reaches your trailer setup and that color-coding aligns with your vehicle’s wiring.
- License plate illumination: If your trailer requires a plate light, confirm whether the kit includes a built-in plate lamp.
- Number of functions: Consider whether you need stop/turn/tail, rear reflectors, side markers, and license plate lighting in one kit.
- Installation complexity: All-in-one kits simplify setup; modular kits may require additional mounting hardware or adapters.
- Durability and seals: Prefer drums or housings with corrosion-resistant materials and moisture seals to maximize longevity in harsh conditions.
- Size compatibility: For trailers under 80 inches wide, ensure the kit is designed for that width and verify mounting hole spacing against your trailer frame.
