CZC AUTO Submersible LED Trailer Light Kit for Trailers up to 80 in — DOT‑Compliant, Fully Sealed

CZC AUTO 12V Submersible LED Trailer Light Kit provides DOT-compliant, fully waterproof tail and marker lighting for trailers up to 80 inches wide, designed to work while submerged.

This all-in-one kit includes left and right multi-function LED tail lights and a marine-grade 18‑gauge copper wiring harness built for boat trailers, utility trailers, snowmobiles and other narrow towing setups. Every diode is an LED (no incandescent bulbs) and the lights are sealed with sonic-welded joints and marine adhesive to resist water intrusion during launch, retrieval and wet-road travel. CZC AUTO backs the kit with a 30‑day money‑back option plus a 12‑month warranty for quality-related issues.

How do these lights perform when submerged or exposed to water?

These lights are engineered specifically for repeated brief submersion and continuous wet conditions. Seams are sonic-welded and sealed with marine-grade glue to block water entry at lens edges and wire entry points, while the harness wiring uses 100% copper for reliable conductivity even when wet.

• Fully sealed housing with sonic welding and marine adhesive
• DOT FMVSS108 certificate—meets standard visibility requirements
• All-LED diodes for bright, long-lasting illumination
• 18-gauge pure copper harness for corrosion-resistant power delivery

What lighting functions are included and how will they help safety?

Each left and right tail light delivers seven functions—stop, turn, tail, rear reflector, side reflector, side marker and license plate illumination—so the kit covers all required signals on small trailers. The high-intensity LEDs increase daytime and nighttime visibility while the reflectors maintain passive visibility if the electrical system fails.

• 7 integrated light functions per lamp for full signaling
• Bright diodes to improve visibility in daylight and darkness
• Reflectors for passive safety when lights are off
• License plate light included—no additional fixture needed

How simple is installation and what comes in the kit?

Installation is straightforward for someone familiar with trailer wiring; the kit ships with a pre-made 18‑gauge copper harness and a wiring diagram to guide connections. CZC AUTO recommends verifying correct wiring and absence of shorts before submersion and provides an instruction sheet for reference.

• Pre-wired 18‑gauge pure copper harness for easier hookup
• Wiring diagram and instruction sheet included in packaging
• Plug-and-play-style connectors compatible with standard trailer systems
• Simple mounting points designed for common trailer frames
