CZC AUTO Submersible Trailer LED Light Kit for Trailers Under 80 in — 7-Function DOT-Compliant Waterproof

The CZC AUTO 12V Submersible LED Trailer Light Kit is a waterproof, DOT-compliant seven-function tail light set designed to stay fully functional when submerged for trailers up to 80 inches wide.

This kit delivers durable, high-visibility LED lighting for boat and utility trailers that may encounter water, mud, or snow. Built with 100% LED diodes, marine-grade seals, and a pure copper 18-gauge wire harness, the lights are engineered for submersion, long service life, and clear signaling on the road. The package includes left and right tail lights with seven integrated functions and a wiring diagram to simplify installation.

How do these lights perform when submerged or in wet conditions?

The CZC AUTO lights use sonic welding and marine-grade glue to seal all possible entry points, keeping water out of the lens and housing. Each unit is inspected photometrically and electrically before shipment to ensure consistent illumination and full function after exposure to water.

• Fully sealed housing with sonic-welded seams and glued wire entrance points
• DOT FMVSS108 compliant for road safety and visibility
• 100% LED diodes for quick response and low heat
• Pre-shipment quality and photometric testing

What functions are included and how will they help while towing?

Each left and right lamp integrates seven functions so you get comprehensive signaling from a single compact unit. These functions provide legal, visible signaling for stopping, turning, side marking, and license plate illumination, reducing the need for additional fixtures.

• Stop lights and turn signals for clear braking and lane-change communication
• Tail lights and side marker lights for visibility in low light
• Rear and side reflectors for passive visibility when lights are off
• Built-in license plate light to meet trailer lighting requirements

Is installation difficult and what wiring should I expect?

Installation is straightforward for anyone familiar with trailer wiring; the kit ships with a wiring diagram and the harness uses 18-gauge pure copper conductors for reliable connectivity. Ensure correct connections and test for shorts before exposing the wiring to water to preserve longevity and function.

• 18 AWG pure copper harness for low resistance and corrosion resistance
• Clear wiring diagram included with the kit and on the instruction sheet
• Simple bolt and screw mounting compatible with common trailer frames
• Recommendation: verify wiring and test lights before submersion
