Full-Featured Trailer Tail Light for Wide-Load Applications — Driver Side
The Seachoice 8-Function Submersible Combination Tail Light is engineered for boat trailers and transport applications where the trailer width exceeds 80 inches. This is the driver side (left) unit, designed to be paired with the Seachoice Universal Mount Combination Tail Light – Passenger Side (7-Function) for a complete rear lighting setup on wide trailers.
The low-profile housing mounts on standard 2-inch centers and is fully submersible — built to handle repeated boat ramp immersion without failure. Acrylic lenses and a corrosion-proof plastic housing keep weight down while standing up to road and water exposure. A shock-mount design protects the bulb from road vibration, extending service life. Stainless steel mounting hardware and a separate ground wire with eyelet are included.

Parts Desk Insights
Best Use Case: This light is the correct choice for wide boat trailers — typically pontoon, tritoon, or large center console trailers — where overall trailer width exceeds 80 inches and DOT regulations require additional clearance and side marker lighting beyond a standard 7-function setup. The 8th function (license plate illumination) makes this a self-contained rear lighting solution without needing a separate license plate light. For the matching passenger side unit, see the Seachoice Universal Mount Combination Tail Light – Passenger Side, 7-Function. For narrower trailers or a simpler setup, the Seachoice 53001 7-Function Driver Side Trailer Light or the Seachoice Submersible LED Combination Light may be a better fit.
