Partsam 6" Rectangular LED Trailer Tail Light Kit Red — Submersible IP68, 25ft 4‑Pin Harness

Partsam 6" rectangular LED combination tail lights are a fully sealed, submersible 12V trailer light kit that provides stop, turn, tail, side marker and license plate illumination with a 25-foot 4‑way harness for easy plug‑in installation.

Designed for boat trailers and general trailer use up to 80" wide, this kit includes two low-profile 5.9" x 3.35" LED rectangular lamps, a 25-foot wiring harness with a standard 4‑pin flat connector, a license plate bracket, stainless fasteners and mounting hardware. The IP68 sealed housings and internal circuit board make the lights suitable for repeated submersion, while distinct diode arrays on each lamp deliver bright, visible signals for braking, turning and running lights.

How are these lights different from standard rectangular trailer lights?

These Partsam lamps are smaller than many 8" rectangular lights and built for submersible use, which makes them especially appropriate for boat trailers or any application exposed to water. Their sealed, screw-free lens design protects the circuit board from moisture and debris.

• Dimensions approximately 5.9" L x 3.35" W x 2.28" H for compact mounting
• IP68 rated sealed housings tested underwater for durability
• Low-profile design reduces snagging and improves clearance

What lighting functions and diode layout does the kit provide?

Each lamp handles multiple functions: stop/brake, left or right turn, running tail light, rear reflex and side marker. The driver and passenger lights have slightly different diode counts to include a dedicated license plate illumination on the driver side.

• Driver side: 23 diodes (14 front, 3 side marker, 6 license plate)
• Passenger side: 18 diodes (14 front, 3 side marker)
• Combined functions: brake, turn, tail, side marker, rear reflex, license plate (driver side)

How do I wire and install the kit on my trailer?

Installation uses the included 25-foot harness with a standard 4‑way flat connector for common trailer wiring systems. Match each colored wire to the trailer circuit, secure the lights with the supplied stainless hardware, and mount the license plate bracket as needed.

• Brown wires: connect to tail/running lights
• Green wire: right turn signal/brake
• Yellow wire: left turn signal/brake
• White wire: common ground/chassis

Will these lights work for my specific trailer or boating setup?

The kit is sized and equipped for trailers under 80" wide; trailers wider than that may need additional side clearance lights. Because the lights are submersible and sealed, they are particularly suited to boat trailers, while still serving general utility and cargo trailers.

• Recommended for trailers under 80" overall width
• Submersible design ideal for boat trailers and wet environments
• Includes mounting hardware and a license plate bracket for quick setup

Who is this for: This Partsam kit is aimed at owners of boat trailers, utility trailers and small to mid-size hauling rigs who need reliable, waterproof lighting with a compact footprint. Choose this set if you want an IP68 sealed solution with a long harness, clear multi-function output and stainless mounting hardware for corrosion resistance in marine or wet conditions.
