CZC AUTO Submersible LED Trailer Light Kit for Under 80" Trailers — 7-Function, Marine-Grade Waterproof

CZC AUTO 12V Submersible LED Trailer Light Kit is a fully waterproof, DOT-compliant set of left and right 7-function LED tail lights engineered for boat and utility trailers under 80 inches wide.

Built for repeated exposure to water, salt, and road debris, this kit combines marine-grade sealing, 100% LED diodes, and a pure copper 18-gauge wiring harness to deliver bright, reliable illumination. The lights are designed for easy wiring and include a wiring diagram and inspection-tested hardware. They meet DOT FMVSS108 requirements and feature multiple reflectors and license-plate illumination so your trailer remains visible and legal in low-light and submerged situations.

How do these lights perform when submerged or in saltwater?

The CZC AUTO lights use sonic-weld sealing and marine-grade adhesive around all seams and wire entry points, protecting internal components from water intrusion. Every unit is tested for photometric output and overall sealing before shipment to ensure consistent performance after repeated submersions.

• Sonic-weld sealing for watertight integrity
• Marine-grade glue at lens edges and wire ports
• 100% LED diodes resistant to shock and vibration
• Pre-shipment photometric and quality inspection

What functions and visibility features do these trailer lights offer?

Each lamp integrates seven functions—stop, turn, tail, rear reflector, side reflector, side marker, and license plate lighting—so a single housing covers all common trailer lighting needs. LEDs provide quicker illumination and higher contrast than incandescent bulbs, improving reaction time for drivers behind the trailer.

• Seven integrated light functions in one housing
• Bright LED diodes for improved visibility and longevity
• Rear and side reflectors built into the lens
• Included license plate light for compliance

Is installation straightforward and what wiring does the kit include?

Installation is user-friendly for DIYers and professional shops alike: the kit ships with a clear wiring diagram and 18-gauge pure copper harness for reliable connections even when exposed to water. Make sure connections are secure and free of shorts before launching your trailer into water.

• 18-gauge pure copper wiring harness for low-resistance connections
• Detailed wiring diagram and instruction sheet included
• Easy mounting with common trailer fasteners (hardware may vary)
• Advice to verify wiring continuity before submersion

What warranty and support does CZC AUTO provide?

CZC AUTO backs the kit with a 30-day money-back policy and a 12-month warranty against quality-related issues, plus customer support that promises a response within 24 hours for troubleshooting. This gives buyers practical recourse if a product arrives damaged or has a manufacturing defect.
