Buying Guide: Key Considerations For Over 80 Inch Trailer Lights
- Waterproofing and IP rating: For over-80-inch trailers, submersible or water-resistant lights (IP67/IP68) are preferred to withstand spray, rain, and immersion.
- DOT/FMVSS-108 compliance: Ensure lights meet regulatory standards for legal operation on highways in the United States.
- Wiring and harness compatibility: Check voltage (12V is standard) and wiring harness included to avoid extra adapters.
- Profile and mounting: Slim, low-profile designs reduce wind resistance and damage risk on wide trailers; confirm mounting hole spacing matches existing plates if upgrading.
- Material and environment: Saltwater environments require corrosion-resistant housings and seals; submersible designs extend life on boat trailers.
- Licensing and license plate lighting: Some kits include license plate lights—essential for legal road use; confirm coverage in your state.
- Maintenance considerations: Look for easy-to-clean surfaces and gasket integrity; plan for routine checks on seals and wiring connections.
- Ease of installation: Kits with all-in-one wiring harnesses and clear instructions simplify the upgrade process, especially for wider trailers.
