Buying Guide
Key purchase considerations
-
<li trailer width compatibility: Ensure the lights are rated for under 80 inches to fit most utility trailers
- waterproofing and submersion rating: Look for IP68 or higher and marine-grade sealing to withstand rain, spray, and submersion
- functionality: Confirm the required signaling functions (stop, turn, tail, license plate, markers) align with the kit or lights you select
- wiring and harness length: Ensure harness length matches your trailer layout; longer runs simplify routing
- installation method: Consider gasketed, welded, or sealed housings and whether a mounting method (stud, screw, or flange) fits your trailer
- certifications: DOT FMVSS108 or equivalent compliance enhances road legality and safety
- durability: Look for corrosion-resistant housings and copper wiring to resist salt and moisture
- maintenance: LED longevity, available replacements, and ease of inspection affect long-term costs
Comparative considerations
- All-in-one kits (like MAXXHAUL) simplify wiring and mounting but may include extra lights you don’t need
- Submersible, all-LED designs maximize durability in marine or muddy conditions but may have different brightness levels
- Licensed lights with left-side license plate illumination provide comprehensive compliance in a single setup
- Sealing technology (sonic welding, marine-grade adhesives) tends to improve water resistance but can increase price
