CZC AUTO Submersible LED Trailer Tail Lights Pair 12V Waterproof DOT-Tested Left & Right

CZC AUTO 12V Submersible LED Trailer Tail Lights are a waterproof left-and-right LED lamp kit that provides stop, turn, tail, reverse, reflector and marker functions for trailers up to 80 inches wide.

These marine-grade trailer lights replace incandescent bulbs with high-visibility LEDs and use sonic-welded sealing plus glued entry points to keep moisture out. The pair includes a left lamp with an integrated license plate light, both built on 18-gauge copper wiring and tested to DOT photometric standards for dependable road and water performance.

How do these lights perform in wet and underwater conditions?

The lights are designed for continuous exposure to moisture and temporary submersion, thanks to full sonic welding and extra glue at vulnerable seams and wire passages. That construction minimizes water ingress and maintains the LED circuit integrity, while copper wiring sustains power transmission when submerged.

• Sonic-welded housing for whole-unit sealing
• Sealed wire entry points and glued lens edges
• 18-gauge pure copper wires resist corrosion and ensure conductivity
• DOT-tested photometric performance for visibility

Which light functions are included and how will they help my trailer setup?

This left-and-right kit supports multiple light roles: stop, turn, tail, rear reflector, side reflector, and side marker functions on both sides, with the left lamp adding a license plate illumination. Using all-LED diodes means faster illumination response, longer service life, and clearer signaling to other road users.

• Stop/Turn/Tail signals for safe towing communication
• Rear and side reflectors improve passive visibility at night
• Left-side license plate light for legal compliance
• All-LED diodes for brighter, longer-lasting output

How easy is installation and what mounting options are available?

Installation is straightforward with two mounting orientations — mount on the trailer back or the side — and a wiring diagram included in the package and online. Ensure proper wiring connections and test for shorts before exposing the assembly to water or submersion.

• Two mounting styles: rear-facing or side-facing
• Wiring diagram supplied in the box and on the product page
• Simple bolt or screw mounting for common trailer frames
• Pre-checked diode assemblies reduce setup troubleshooting

What quality assurances and compatibility should I expect?

CZC AUTO inspects each LED diodes assembly, including photometric testing, to meet visibility standards and offers a warranty and return policy for peace of mind. The kit fits towing platforms up to 80 inches wide, such as boat trailers, utility trailers, snowmobile trailers, and light trucks.

• 100% diode quality inspection before shipment
• DOT-standard photometric testing by U.S. labs
• 30-day money-back and 12-month limited warranty
• Recommended for trailers under 80-inch width
