Buying Guide: Key Considerations For Choosing A Trailer Tail Light Kit
- Trailer size compatibility: Most kits cover trailers under 80 inches. Confirm width and mounting points before buying.
- Light type: LED vs incandescent. LEDs last longer and are more visible in rain or fog; incandescent kits are typically less expensive but require more frequent replacements.
- Waterproofing and submersion: For boats or water-adjacent trailers, prefer IP67/IP68 ratings and submersible construction.
- Wiring harness length: Longer harnesses (22–25 ft or more) suit longer trailers and better access to power sources. Ensure the harness color-coding matches your trailer wiring.
- DOT/FMVs compliance: If legal road use is required, look for DOT/FMVS108 or equivalent compliance to ensure inspection acceptance.
- Ease of installation: Split Y-style or color-coded harnesses simplify wiring. Verify included mounting hardware and license plate provisions.
- Compatibility with existing components: Check license plate light, reflectors, and alignment with your trailer’s current hardware.
- Maintenance and serviceability: Consider kits with sealed, screwless lenses and proven sealing methods for long-term reliability.
