Partsam 6" Rectangular LED Combination Tail Lights Kit — Red, IP68 Submersible with 25ft 4‑Way Harness

Partsam 6" rectangular submersible LED tail light kit is a sealed, 12V combination stop/turn/tail/license light system with a 25-foot 4-way harness built for boat trailers and general-purpose trailers up to 80" wide.

This kit delivers a compact, durable lighting solution intended for trailers that encounter wet conditions, including boat trailers that may be submerged. Each sealed lamp packs multiple LEDs for visible stop, turn, tail and marker functions, while the included 25-foot wiring harness with a standard 4-way flat connector and license plate bracket simplifies installation. The set is sized for trailers under 80" wide and includes mounting hardware and a stainless steel screw for long-lasting attachment.

How waterproof and durable are these lights?

These LED units are designed with a fully sealed circuit board and no external screws on the lens surface, giving them IP68-level submersibility suitable for temporary immersion. Partsam reports a 24-hour underwater test, and the sealed construction minimizes corrosion risks and water intrusion often found on boat trailers.

• IP68-style sealed enclosure for temporary submersion
• No exposed screws on the lens to prevent leaks
• Stainless steel mounting screw included to resist rust
• Durable LED chips rated for extended outdoor use

What lighting functions and diode layout does the kit offer?

Each rectangular lamp serves multiple roles: stop/brake, turn signal, tail light, rear reflex, side marker and, on the driver side, a license plate lamp. The driver side contains 23 diodes (14 front, 3 side marker, 6 license plate) while the passenger side contains 18 diodes (14 front, 3 side marker), ensuring clear, multi-function visibility.

• Driver side: 23 LEDs with integrated license plate illumination
• Passenger side: 18 LEDs for consistent brake/turn/tail output
• Built-in red side markers and rear reflexors
• Measuring approximately 5.9" L × 3.35" W × 2.28" H for compact fit

How is the kit wired and how easy is installation?

Installation is straightforward for anyone familiar with standard 4-way trailer wiring. The kit includes a 25-foot pre-assembled wiring harness with a standard 4-pin flat connector, plus mounting hardware and a license bracket, so you can mount the lights and connect them to an existing trailer harness quickly.

• 25 ft wiring harness with standard 4-way flat connector included
• Brown wires for tail lights; green for right brake/turn; yellow for left
• White wire for common/chassis ground; plug-and-play for most trailers
• Mounting bolt, stainless screw and hardware supplied

Will these lights fit my trailer and when should I choose a different kit?

The compact rectangular shape and 5.9" length make these lamps suitable for most utility and boat trailers that are under 80" wide. If your trailer requires amber side clearance lights or exceeds 80" width, you may need additional side markers or a different low-profile kit that includes amber side lights to meet regulations.

• Recommended for trailers under 80" wide without separate amber side lights
• Use additional side clearance lights if trailer width exceeds 80"
• Choose low-profile rectangular kits if your trailer lacks amber side markers
• Compact size helps on tight mounting surfaces and rear bumpers

Who is this for: The Partsam 6" rectangular LED tail light kit is aimed at boat owners, small utility trailer users and anyone who needs a submersible, multi-function rear lighting solution that’s easy to install. It’s especially useful for trailers that see regular exposure to water, require a visible license plate light on the driver side, and benefit from a pre-wired 25-foot harness for convenient installation.
