Gonice Complete LED Trailer Light Kit Full Function Kit, Submersible Square Tail Lights with Brake Light Bar and 6 Marker Lights

Gonice Complete LED Trailer Light Kit is a full, submersible lighting system that replaces tail, brake, marker and license plate lights for trailers, trucks, RVs and boats.

This all-in-one kit bundles square LED tail lights, a welded brake light bar, six marker lights, a wiring harness and mounting hardware so you can upgrade a trailer’s exterior lighting in one install. The LEDs are designed for long life and low power draw, and the sealed construction resists water, dust and road debris—making the set suitable for towing, marine and year-round outdoor use.

What components come in the Gonice trailer light kit?

The kit includes everything needed to swap or retrofit most 12V trailer lighting systems under 80 inches wide. It’s packaged to minimize trips to the hardware store and simplify installation for DIYers and pros alike.

• 2 square red LED tail lights (running/stop/turn/reverse)
• 6 amber/clear marker/clearance lights
• 1 welded LED brake light bar with integrated reflectors
• Complete wiring harness, license plate bracket and mounting hardware

How do these lights perform in wet or marine environments?

All major components are welded and sealed to prevent water intrusion, allowing the kit to function after brief submersion and resist splashes, salt spray and road slush. That construction helps maintain consistent lighting performance in adverse conditions.

• Welded housing and sealed lenses for water resistance
• Corrosion-resistant materials for marine exposure
• Designed to handle snow, dirt and salt spray

Will this kit fit my trailer or vehicle?

The Gonice kit is engineered for broad compatibility with most 12V trailers and vehicles up to about 80 inches wide. Its mounting hardware and universal wiring harness make it adaptable to common trailers, campers, utility rigs and small trucks.

• Fits trailers, RVs, trucks, dump trailers, snowmobiles and tractors
• Universal wiring harness for standard 4-to-7-pin systems
• Mounting brackets and screws included for typical installations

How energy-efficient and durable are the LEDs?

LEDs use substantially less current than incandescent lamps while delivering bright, uniform signaling. The expected lifespan and low energy draw reduce maintenance and keep trailer batteries under less strain during long hauls.

• Long-life LEDs rated for approximately 50,000 hours
• Low current draw extends battery and circuit life
• High-visibility red and amber outputs for improved safety

Who is this for? Installers, fleet managers and DIY trailer owners who want a single purchase to replace multiple lighting components will find this kit useful. It’s particularly well suited to those who need weatherproof, bright signaling on trailers, boats, campers or utility vehicles and prefer a bundled solution that includes harnessing and hardware for a cleaner, faster installation.
