Jamarco 6" Oval LED Trailer Tail & Backup Light Kit — 2 Lamps, 25ft 5‑Pin Harness, Steel Brackets

Jamarco's 6" oval LED trailer light kit supplies two combined stop/tail/turn lights with built-in reverse LEDs, a 13.8" third brake light bar, six low-profile side marker lights, reflective stickers and a 25ft 5-pin wiring harness for a complete trailer rear lighting solution.

This all-in-one set is designed to replace or upgrade trailer rear lighting with bright LEDs, corrosion-resistant steel brackets and a long wiring harness for easier installation. The components are universal for 12V DC trailers, campers, trucks and many utility vehicles. Below you’ll find practical details on what’s included, how key parts work, and considerations for fit and wiring.

How do the 6" oval lights serve both tail and reverse functions?

Each 6-inch oval lamp integrates 23 LEDs: red diodes for tail/stop/turn signals and white diodes dedicated to backup illumination. A dedicated bullet-style plug and an extra wire power the reverse LEDs separately from the running/stop circuit, so both functions operate independently.

• 23 LEDs per oval (16 red + 7 white) for high visibility
• Separate white wire with 180° male bullet plug for reverse light
• Color-coded wiring: white = ground, red = stop/turn high brightness, black = tail/low brightness
• Included heavy-duty steel mounting brackets for secure fit

What wiring and connector options are included?

The kit includes a 25-foot wiring harness with a 5-pin flat plug tailored for oval lights that have a separate reverse circuit. That longer harness simplifies routing back to the trailer plug and reduces the need for splicing extension cables.

• 25 ft 5-pin flat harness compatible with dedicated reverse wire
• Color-coded harness leads to match light wires for faster hookup
• Extra connectors and clearly labeled wires to avoid confusion
• Instructions and wiring tips for correct ground and power connections

Are the lights durable and weather resistant for outdoor use?

The LEDs and mounting hardware are designed for exterior use on trailers and work vehicles, featuring sealed light housings and steel brackets with protective coating. These components resist moisture and road conditions better than traditional incandescent bulbs, though proper mounting and grounding remain important for longevity.

• Waterproof LED housings suitable for road and marine exposure
• Heavy-duty steel brackets with anti-corrosion coating
• Low-power LEDs reduce heat and bulb-failure risk
• Reflective stickers included to increase nighttime visibility

What else is included and what do the smaller marker lights do?

The kit bundles six mini LED marker/clearance lights (four red, two amber red per description), plus a 13.8" 15-LED third brake identification light. The marker lamps provide side and corner visibility while the light bar adds a center brake/identification signal for compliance and added safety.

• Six mini side marker lights for clearance/side visibility
• 13.8" 15-LED third brake/identification light bar surface-mounts on trailers
• Four reflective stickers to complement passive visibility
• Simple wiring color codes: marker white = ground, black = positive

Who is this for: This kit fits owners who want a single purchase to upgrade a trailer’s rear lighting system — including DIY trailer builders, fleet maintenance crews, RV and camper owners, landscapers, farm operators and anyone replacing worn incandescent fixtures. It’s aimed at people seeking brighter LED visibility, a dedicated reverse light circuit, and a long harness to simplify installation across most 12V trailer applications.
