CZC AUTO 12V Submersible LED Trailer Light Kit — Under 80" Trailers, DOT-Sealed Marine-Grade

CZC AUTO 12V Submersible LED Trailer Light Kit provides fully sealed, DOT-compliant tail, stop, turn, marker and license plate lighting designed for trailers under 80 inches wide, including boat and utility trailers.

This kit delivers a purpose-built lighting solution for small trailers that need dependable illumination both on-road and while launching or retrieving in water. Every component is engineered for marine exposure: sonic-welded housings, marine-grade sealant at all entry points, and a 100% LED design fed by 18-gauge pure copper wiring. The result is a compact, bright lighting package that meets DOT FMVSS108 standards and resists submersion without sacrificing visibility.

What functions do the left and right lights perform?

Each side combines multiple lighting roles in one sealed unit so you don't need extra fixtures. The integrated design covers all required signals for safe towing and regulatory compliance.

• Stop and turn signals for directional control.
• Running/tail lights for night visibility.
• Rear and side reflectors plus side marker illumination for lateral visibility.
• Integrated license plate light so the plate stays visible when mounted.

How is the kit protected against water and salt exposure?

Protection is built into both material choice and assembly technique. CZC AUTO uses sonic welding plus marine-grade adhesives to seal every vulnerable gap, including wire entrances and lens edges, to keep moisture out.

• Sonic-welded housing to prevent seam leaks.
• Marine-grade glue at wire entry points and lens edges for added seal integrity.
• All LED diodes avoid heat and failure modes common to incandescent bulbs.
• Design tested for submersion and visual photometric inspection before shipping.

What makes the wiring and LEDs reliable for underwater use?

The harness and light electronics emphasize corrosion resistance and electrical continuity under wet conditions. Using thicker, pure copper wiring reduces voltage drop and stands up to repeated submersions.

• 18-gauge 100% pure copper wire harness minimizes resistance and corrosion issues.
• All LED diodes—no incandescent bulbs—extend lifespan and maintain brightness.
• Full quality and photometric inspection before shipment ensures consistent output.
• Wiring diagram included to prevent shorts during installation.

How easy is installation and what support is included?

Installation is straightforward for basic trailer wiring projects; the kit includes a wiring diagram and clear instructions. CZC AUTO also offers responsive customer service and a warranty for peace of mind.

• Simple wiring diagram shipped with the lights and included in the instruction sheet.
• Check connections and avoid shorts before submersion—basic electrical steps recommended.
• 30-day money-back guarantee and 12-month warranty for quality-related defects.
• Customer support promise: contact CZC AUTO for troubleshooting within 24 hours response.

Who is this for: This submersible LED light kit suits owners of small boat trailers, utility trailers, snowmobile trailers, and compact towing rigs under 80 inches wide who need durable, DOT-compliant lighting that withstands freshwater or saltwater exposure. It's also a good fit for DIY trailer builders and marine-service technicians seeking a sealed, low-maintenance lighting solution that reduces corrosion-related failures and preserves visibility during launches and trailered transport.
