Partsam Submersible LED Trailer Tail Light Kit, Rectangle 12V — 25ft Harness, IP68 Halo-Glow

Partsam Low Profile Submersible LED Trailer Tail Light Kit is a sealed, rectangular 12V LED assembly with Halo-Glow running lights, integrated stop/turn/tail functions, and a 25-foot wiring harness designed for trailers and marine use.

This compact, low-profile kit combines multiple functions into each housing while resisting full submersion and harsh weather. It ships with two rectangular stop/turn/tail lights (one with a license plate illuminator), two amber clearance markers, a full 25-foot 4-pin wiring harness plus a secondary short harness, mounting hardware, and reflective stickers. The lights use a patented Halo-Glow ring for a continuous running-light appearance and are built to fit common 80-inch-wide trailer applications.

How does this kit hold up when launching or retrieving a boat?

The lights are rated IP68 and feature a fully sealed circuit board, so they tolerate immersion and continuous exposure to water better than standard trailer lamps. That makes them suitable for boat trailers that frequently enter shallow water or encounter heavy spray.

• IP68 waterproof rating for submersion resistance
• Sealed PCB to prevent diode and circuit corrosion
• Stainless-steel mounting hardware included for corrosion resistance

What wiring and connections are included, and how do I wire them?

The package contains a 25-foot 4-pin wiring harness plus an additional short harness to connect the lamps to the tow vehicle. Each function uses separate color-coded wires so you can hook up running lights, brakes, and turn signals without splicing multiple circuits together.

• 25ft harness for trailer-side routing and a short 3.93ft harness for vehicle-side connection
• Brown wires for tail lights; green for right turn/brake; yellow for left turn/brake; white for chassis ground
• Separate wiring for the amber clearance lights (red positive and black ground)

How visible and functional are the lights for everyday towing?

The LEDs produce bright, distinct signals for stop, turn, and tail functions while the Halo-Glow running ring creates a continuous, smooth light signature that improves daytime and nighttime visibility. One light also includes a built-in license plate illuminator so your plate remains visible when towing at night.

• Rectangle housings combine stop, tail, turn, reflectors, and side marker roles
• Patent Halo-Glow ring for a solid running-light appearance
• Left lamp includes integrated plate illumination for legal visibility

Will these lights fit my trailer and how hard are they to install?

The kit is made to suit common 80-inch-wide trailers and a wide range of vehicle types including trucks, RVs, utility trailers, and boat trailers. The low-profile housings mount with the supplied screws and bolts, and clear color-coded wires simplify the connection process for DIY installation.

• Designed for 80" width vehicles: trucks, trailers, campers, boats, and more
• Low-profile design reduces snagging and improves clearance
• Comes with mounting screws, bolts, license plate bracket, and reflective stickers

Who is this for? This Partsam kit is aimed at trailer owners who need dependable, compact lighting that stands up to water exposure—boat trailers, utility trailers, pickup owners, and small commercial fleets. It's also a good choice for anyone replacing worn or non-waterproof lights with a sealed, multi-function LED solution that includes wiring and mounting hardware for a faster retrofit.
