What the AI looks for in Boat Trailer Lights
- LED, sealed and submersible
- Choose sealed LED units that are rated as submersible Incandescent bulbs crack when a hot bulb hits cold water, and their sockets corrode.
- Road-legal compliance
- Lights should be marked DOT and SAE compliant Unmarked lights can fail inspection or be too dim.
- Trailer width
- Trailers 80 inches wide or wider need additional clearance and identification lights This is a US federal lighting requirement for wide trailers.
- Connector and ground
- A 4-way flat connector matching the vehicle, and a dedicated white ground wire rather than a frame-only ground A bad ground causes most trailer light failures.
Brands that matter
- Optronics: LED trailer lighting specialist.
- Wesbar: Long-time boat trailer lighting brand.
- Peterson Manufacturing: Major vehicle and trailer lighting maker.
What to avoid
- Non-sealed incandescent lights on boat trailers
- Relying on the trailer frame as the only ground
- Non-marine butt connectors with no heat-shrink seal
