Traberm LED Trailer Tail Light Kit — 2pc Square Stop/Turn/Tail Lights with 15.5" Brake Bar and 25ft Harness, Sealed LEDs

Traberm LED Trailer Tail Light Kit is a complete 12V lighting package that includes two square stop/turn/tail lights, a 15.5" third brake light bar, mini side markers, a 25ft wiring harness and mounting accessories.

This kit supplies everything needed to upgrade or replace a trailer's exterior lighting with sealed, high-visibility LEDs rated for wet conditions. Components are designed to work with standard 4-flat trailer wiring and fit most 80-inch (and narrower) trailers, RVs, trucks and utility equipment. The lights combine multi-function diodes, a license plate lamp, and a long harness so installation reaches the trailer tongue without splicing.

How bright and durable are the LEDs for road and wet-weather use?

The lamp heads use multiple diodes to serve stop, turn, tail, and reflector duties while remaining visible in rain or spray. Circuit boards are sealed so moisture won't short the assemblies even when exposed to harsh outdoor conditions.

• Square lights: 12 diodes each for stop/turn/tail and reflex functions.
• 15.5" bar: 11 LEDs for high‑visibility center brake/turn/tail signaling.
• Mini oval markers: 3 diodes each for clearance/side marking.
• Fully sealed housings for water resistance and longer life.

What comes in the kit and will it fit my trailer's wiring?

The package includes the two square rear combination lights, a 15.5" tail light bar with base, two mini side markers, a 25ft 4-flat wiring harness, license plate light bracket, mounting screws and reflective stickers. The harness uses a standard 4-flat plug that mates with almost all 12V trailer connectors.

• Complete 12V kit: rear lights, bar, side markers, harness and hardware.
• 25ft harness reaches most trailer tongues without cutting wires.
• 4-flat connector compatible with standard towing setups.
• Wires labeled: ground, brake/turn, and running lights for straightforward hookup.

How simple is installation for a DIYer?

Wiring is color-coded and documented so a basic hand‑tools installer can mount and connect the lights in a few hours. The kit includes mounting screws and a license plate bracket to minimize additional purchases.

• Color-coded leads: white ground, yellow brake (square), red running, etc.
• Surface-mount bar with base for easy placement and stable mounting.
• Included hardware and reflective stickers for code-friendly installation.
• Lifetime technical support from Traberm if you need help.

Will these lights work on trucks, RVs, and boats?

Yes — the lights are specified for 12V systems and suit trailers, campers, trucks, tractors, buses and many boat trailers. The sealed circuit design protects against water exposure, making them suitable for marine trailering applications as well.

• Compatible with most 12V vehicles up to 80" wide.
• Submersible-ready sealed boards for splash and puddle resistance.
• Works with utility trailers, campers, snowmobiles, and more.
• Universal 4-flat harness for broad vehicle compatibility.

Who is this for: The Traberm LED Trailer Tail Light Kit is intended for trailer owners, DIY mechanics and fleet managers who want a reliable, visible, weather‑resistant lighting solution that installs with minimal modification. It's useful when replacing worn incandescent lights, upgrading to LEDs for greater brightness and longevity, or wiring a new trailer that needs a full rear lighting set.
