Seachoice 52921 Submersible Trailer Light Set — For Trailers Over 80"
A matched two-light set designed for wide boat trailers over 80 inches in overall width. Both lights are fully submersible — built to handle repeated launch ramp immersion without water intrusion or corrosion failure. The set covers all required lighting functions across both sides, with the driver-side light adding license plate illumination to the 7-function passenger-side configuration.
Stud mount on 2″ centers with ground-through-stud wiring keeps installation clean, and the screw-on lens design makes bulb replacement straightforward without special tools. Corrosion-resistant hardware throughout. Meets SAE, DOT, FMVSS, and CMVSS standards when properly installed.

- 1 × Passenger side light — 7-function: stop, turn, tail, rear clearance, rear reflex, side marker, side reflex

Parts Desk Insights
Best Use Case: The right choice for wide boat trailers — typically dual-axle or pontoon trailers — where the overall trailer width exceeds 80 inches and regulations require lights mounted at or near the outermost edges of the trailer. Buying as a matched set ensures consistent lens color, housing style, and function count across both sides. The submersible rating is the key differentiator here: if your trailer goes into the water at launch, non-submersible lights will fail prematurely from water intrusion. For trailers under 80 inches wide, see the individual driver and passenger side lights linked above.
