CORINTH 12V Submersible Square LED Trailer Tail Light Kit, 25' Harness — Waterproof DOT/SAE Compliant

This compact kit supplies left and right LED lamps built to replace incandescent trailer lamps with brighter, longer-lasting illumination. The lights meet DOT/SAE standards for standard trailer mounting positions and are engineered to resist moisture during towing, launching, or rainy conditions. Included is a 25' wire harness so you can mount lights on a variety of small trailers, utility haulers, or boat trailers with clear, reliable signal performance.

How does this LED kit improve visibility compared with incandescent bulbs?

LEDs produce a more distinct, faster-responding light than incandescent lamps, improving how quickly following drivers see brake and turn signals. The design concentrates light output so tail, stop, and turn signals stand out against road or water reflections.

• Higher brightness for clearer brake and turn indication
• Faster illumination response time than filament bulbs
• Lower power draw reduces load on vehicle electrical systems
• Longer expected lifespan than standard incandescent lamps

Are these lights suitable for wet or submersible conditions?

Yes — the CORINTH AUTO 12V tail lights are built to be submersible and resist common water exposure encountered on boat ramps and wet roads. Sealing and housing materials minimize water ingress so the circuit and LEDs maintain functionality after splashes or temporary submersion.

• Gasketed housing and sealed lens construction
• Corrosion-resistant contacts for marine or wet environments
• Designed to withstand short-term submersion during launching

What comes in the kit and how easy is installation?

The kit includes two square LED lights (left and right) plus a single 25-foot wire harness ready for standard trailer light mounting locations. Installation is straightforward for anyone comfortable with basic trailer wiring and mounting hardware; the long harness lets you position the lights on a variety of frame widths without splicing additional cable.

• Left and right square LED tail lights included
• 25' pre-wired harness for flexible placement up to 80" wide trailers
• Fits standard mounting holes—minimal drilling or adapter plates may be needed

Will these lights meet legal standards for trailers?

CORINTH designed the AUTO 12V kit to meet applicable DOT/SAE standards for stop, tail, and turn signal function in standard mounting positions. Always confirm local regulations for light placement and lens color before installation to ensure compliance.

• Manufactured to meet DOT/SAE requirements
• Appropriate for common trailer light positions and signal use
• Check local rules for additional reflector or side-marker needs

Who is this for: This CORINTH submersible LED tail light kit is aimed at boat owners, small trailer and utility trailer users, and towing DIYers who need a durable, brighter alternative to incandescent lamps. It’s especially useful if you launch boats frequently, haul gear in wet conditions, or want a low-maintenance, DOT/SAE-compliant lighting upgrade for trailers up to 80 inches wide.
