Partsam Submersible Under 80ft LED Trailer Light Kit - Complete

In this review of the Partsam Submersible Under 80' LED Trailer Light Kit the bottom line is practical: it is a complete, bright lighting upgrade for trailers, campers and small trucks that need a single-package replacement. The kit includes square combination tail lights, a 15' identification brake bar, six mini side markers, a 25ft 4-flat wiring harness, license plate bracket and mounting hardware, so the biggest reason to buy is convenience - everything required for a full rear lighting replacement is in the box and designed to be weatherproof for outdoor use.

Key Features

• Complete kit: Includes two square combination tail lights, six mini oval side markers, a 15' third brake ID bar, 25ft wiring harness, license plate bracket and mounting hardware so users can swap out all rear lights in one job.
• Multi-function lights: Each combination light handles running, stop, brake, turn signal and reverse duties so the kit covers standard trailer lighting needs without extra parts.
• High brightness LEDs: Advanced LED arrays with multiple diodes provide brighter output and better heat distribution than halogen, improving visibility in poor weather.
• Waterproof construction: Fully sealed housings and screw-reduced lenses prevent water intrusion, protecting the circuit board from sand, dirt, snow and moisture.
• Long wiring harness: The included 25ft 4-flat harness reaches most trailer lengths under 80' and simplifies connection to the tow vehicle.

Who It's For

This kit suits owners of small trailers, utility trailers, campers, snowmobile trailers and small boats who want a one-box solution to replace or upgrade rear lighting on vehicles with a 12V electrical system and an overall trailer width near 80'. Its waterproof design and bright LEDs make it a good choice for those who tow in wet or winter conditions.

Those seeking OEM-specific connectors, unique mounting dimensions, or commercial heavy-duty fleet components should look elsewhere; the kit prioritizes universality and value over vehicle-specific plug-and-play fitment or industrial-grade connectors.
