Buying Guide: Key Purchase Considerations
- Trailer size and compatibility: Under-80″ trailers typically use compact, low-profile lights. Verify mounting distance and space for wiring harness routing.
- Waterproof and submersible rating: IP68 is ideal for boat trailers; IP67 offers strong splash protection. Consider saltwater exposure and the need for salt spray resistance.
- DOT FMVSS108 compliance: Ensures legality and standardized brightness, signaling, and reliability on public roads. Look for explicit DOT references in product literature.
- Function set: Decide whether you need six, seven, or more functions (stop, turn, tail, license plate, reflectors, brake bar). Some kits include a third brake light for extra rear visibility.
- Wiring and harness length: Longer harnesses (like 25 ft) help with larger trailers. Ensure wiring gauge (18 AWG copper) is suitable for the expected current draw.
- Materials and sealing: Sonic welding and marine-grade sealants reduce water intrusion. Corrosion-resistant hardware extends life in marine environments.
- Installation considerations: Some kits require additional mounting brackets or hardware. Check for included screws, brackets, and ground connections.
