Partsam LED Trailer Light Kit Submersible Under 80" — 25ft Harness, Square Stop/Turn/Tail & Red/Amber Markers

Partsam Submersible Under 80" LED Trailer Light Kit is a complete 12V lighting package that replaces tail, turn, stop, reverse, side marker and third-brake functions for trailers up to about 80 inches wide.

This all-in-one kit bundles two square combination stop/turn/tail lights, six mini oval side fender markers (two red, four amber), a 15-inch third brake identification light bar, a 25-foot 4-flat wiring harness with plug, a license plate bracket, and mounting hardware. Each lamp uses multi-diode LED arrays with sealed housings for weather resistance, so you can upgrade visibility and system reliability in one installation session.

How does this kit improve trailer visibility in traffic and poor weather?

The LED arrays deliver brighter, faster-responding illumination than incandescent bulbs, making brake and turn signals more noticeable. Sealed, submersible housings prevent water or dust intrusion, preserving light output in rain, snow, or dusty conditions.

• High-count LED diodes for stronger, more uniform light
• Reflectors integrated into combination lights to enhance conspicuity
• Fully sealed construction resists water, dirt and corrosion

What functions and lamp types are included in the package?

The kit covers all standard exterior trailer lighting roles: running/tail, brake, turn signal, reverse illumination on the street-side combo, side marker and reflector duties, license plate lighting, and a center identification/third-brake bar. The components are ready to mount and wire with the supplied 25-foot harness and 4-flat plug.

• 2 square combo stop/turn/tail lights (curb and street side differences included)
• 6 mini oval side fender marker lamps (2 red, 4 amber)
• 15" LED identification/3rd brake light bar and license plate bracket
• 25 ft wiring harness with 4-flat plug and mounting hardware

How easy is installation and will it fit my trailer under 80" wide?

The kit is designed for straightforward replacement or upgrade of existing 12V trailer lighting systems. The long 25-foot harness reaches the front of most trailers, and mounting hardware plus bracket make placement of the third-brake lamp and license light simple.

• Standard 4-flat connector plugs into common trailer wiring systems
• Mounting hardware and license plate bracket included for quick setup
• Intended for trailers, campers, boats and vehicles roughly 80" wide or less

How durable are the lights and what maintenance is required?

LEDs and sealed housings reduce routine upkeep compared with bulb systems. The screws are removed from the lampshade design to minimize leak points, and the materials resist corrosion, so you should need only periodic cleaning and inspection of wiring connections.

• Sealed, submersible housings cut down water and dirt exposure
• LED units run cooler and last longer than halogen/incandescent bulbs
• Recommended: inspect connectors and mounting fasteners seasonally

Who is this for: This Partsam kit suits owners of small trailers, utility trailers, campers, snowmobiles, boats or trucks who want a single, weather-resistant lighting overhaul. It's ideal if you need a full replacement set—including side markers and a 3rd brake bar—with a complete harness and hardware for quick, reliable installation on vehicles with approximately 80 inches of width.
