CZC AUTO 12V Submersible LED Trailer Tail Lights, Left & Right Set — Waterproof 6-Function

Designed for boats, utility trailers, snowmobiles and small trucks, this left-and-right LED light set replaces incandescent units with long-lasting diodes, sealed housings and built-in reflectors. Every lamp undergoes inspection and photometric testing to meet visibility expectations, while robust construction lets the lights remain functional even when submerged. The kit includes two lamps, pre-attached 18-gauge copper wires and a wiring diagram to simplify installation.

How do these lights perform in wet or submerged conditions?

The lights use sonic-welded full-seal construction plus glue-sealed entry points to prevent water intrusion. That combination protects internal electronics and diodes so the lamps maintain brightness after exposure to rain, splash or temporary submersion.

• Full sonic-weld sealing around the housing for durability.
• Glue sealed wire inlets and lens edges to block leaks.
• 18-gauge pure copper wiring rated for marine or wet environments.
• DOT-tested photometric inspection for visibility standards.

Which lighting functions are included and how are they arranged?

Both left and right lamps combine several functions in a compact lens: stop, turn, tail, rear reflector, side reflector and side marker. Additionally, the left lamp includes a built-in license plate light for legal rear illumination.

• Stop/turn signals integrated into one LED array.
• Tail light plus side marker for nighttime visibility.
• Rear and side reflectors molded into the lens for passive recognition.
• Left lamp includes the license plate light for compliant rear lighting.

How easy is installation and what mounting options exist?

Installation is straightforward with two mounting orientations: rear (back-facing) or side (edge-facing), depending on trailer design. The set ships with a wiring diagram, and pre-stripped 18-gauge copper wires simplify connections; verify correct wiring and avoid shorts before submersion or marine use.

• Two mounting options: back or side mount to fit different trailer frames.
• Pre-attached 18-gauge copper lead wires for secure electrical connections.
• Included wiring diagram for quick reference during installation.
• Recommend electrical check before exposing to water.

What durability and quality checks support the product?

Every lamp undergoes a 100% inspection process including photometric testing to ensure brightness and functional reliability. Using LEDs instead of incandescent bulbs lowers failure points and extends functional life under vibration and moisture exposure.

• All-diodes LED design for longer lifespan and consistent light output.
• 100% quality and photometric inspection before shipping.
• Marine-grade sealing and corrosion-resistant components.
• DOT-compliant testing completed by a U.S. lab.
