Optronics Submersible Trailer Light Kit

Ensure your trailer remains safe, visible, and legally compliant on every journey with the OPTRONICS Submersible Trailer Light Kit. Engineered for exceptional performance and durability, this all-in-one kit is the perfect solution for replacing or upgrading the lighting on your boat, utility, or cargo trailer, especially those frequently exposed to water. Built with Optronics´ renowned quality, this kit provides a reliable lighting system that withstands the rigors of the road and marine environments.

The primary benefit of this kit is its fully submersible design. Thanks to a sonically sealed, waterproof construction, these lights are guaranteed to prevent water intrusion when launching and retrieving boats or driving through heavy rain. This "bell jar" principle means the airtight lens and housing protect the bulb and internal wiring from moisture and corrosion, dramatically extending the life of your lights and preventing frustrating failures. The rugged, high-impact polycarbonate material used for both the lens and housing offers superior resistance to cracks, fading, and damage from road debris, ensuring long-lasting clarity and protection.

This comprehensive kit is designed for convenience and safety. It provides all the necessary functions for trailers under 80 inches wide, including stop, tail, and turn signals, with the driver-side light also featuring a built-in license plate illuminator. Meeting all DOT FMVSS 108 requirements, you can tow with the confidence that you are fully compliant with road safety standards.
