Partswcgg Submersible LED Trailer Tail Light Kit 12V — 25ft Wiring Harness, IP68 Waterproof

Partswcgg Submersible LED Trailer Tail Light Kit is a complete 12V lighting set — waterproof, multi-function lights with a 25ft wiring harness designed to replace or upgrade trailer lighting in one install.

This kit bundles everything needed to modernize trailer lighting: two rectangular flag-design combination tail lights, an illuminated 13.8" third brake/tail bar, eight mini oval side marker lights, reflective stickers, license-plate bracket, mounting hardware and a 25-foot wiring harness with a 4-flat plug. Each component is IP68-rated for submersible use so the assembly stands up to wet conditions found on boat trailers, utility trailers, campers and heavy equipment. The set addresses stop, turn, tail and marker needs while keeping installation straightforward for DIYers and installers alike.

How does this kit handle wet or marine environments?

All lamp housings and internal circuitry are sealed to IP68 standards, meaning they resist prolonged submersion and keep moisture out of the LEDs and circuit board. The fully encapsulated construction minimizes corrosion and electrical failure in salty or fresh water exposure.

• IP68 submersible rating for long-term water resistance
• Sealed housings and gaskets to prevent ingress
• Corrosion-resistant materials suited for marine use
• Built-in license plate light on driver side stays dry and functional

What lighting functions are included and how bright are they?

The kit combines multi-function rectangular lights, a 13.8" LED tail/bar and mini oval side markers to cover stop, turn, tail, clearance, reflex and license-plate illumination. The rectangular tail lights use 24 diodes each and the bar contains 11 LEDs, delivering high visibility for braking and signaling while the mini markers provide steady running/clearance illumination.

• Rectangular combo lights: 24 diodes for stop/turn/tail and reflex functions
• 13.8" LED tail bar: 11 LEDs for brake, tail and turn signaling
• Mini oval markers: 2 diodes each for side clearance and running light duties
• Driver-side license plate LED cluster to illuminate plate clearly

How is the kit wired and how does the 25ft harness simplify installation?

The included 25-foot wiring harness (22ft plus 4ft lead) terminates in a standard 4-flat plug for trailer-to-vehicle connection. Color-coded leads and clear wiring notes reduce guesswork: dedicated grounds, brake/turn high-brightness lines, and lower-brightness running-light circuits make it easier to match to most 12V trailer systems.

• Standard 4-flat plug for universal trailer connection
• Color-coded wires: ground, high-brightness brake/turn, low-brightness running
• 22ft main harness plus 4ft extension for flexible routing
• Clear wiring tips included for each lamp type

What mounting supplies and extras come in the box?

The kit includes the brackets and fasteners required for surface-mounting the lights along with a license-plate bracket and reflective stickers to meet visibility and safety expectations. These extras reduce the need for separate purchases and let you finish a full trailer lighting upgrade in one session.

• Mounting hardware and surface-mount brackets for tail bar and combination lights
• License-plate bracket with built-in illumination from driver-side unit
• Four reflective stickers for added rear visibility
• Installation-ready parts to avoid extra trips to the hardware store

Who is this for: The Partswcgg Submersible LED Trailer Tail Light Kit is made for boat owners, RV and utility trailer operators, fleet managers and anyone who needs durable, all-in-one trailer lighting that survives wet conditions. It suits DIY installers and professionals who want a weatherproof, code-friendly lighting set with a long wiring reach and the parts needed to finish a full upgrade in a single purchase.
