Jamarco Trailer LED Tail Light Set – 2-Piece Square Red Rear Combination with License Lamp

Jamarco's 2-piece square red LED rear combination tail lights are a ready-to-install, 12V lighting solution combining tail, brake, turn, side marker, reflector and (left unit) license-plate illumination in one compact housing.

These square LED combination lights are built for trailers under 80 inches wide and come as a matched left-and-right set with mounting hardware included. Each lamp is a surface-mount unit designed to hardwire into standard trailer circuits using the three-wire pigtail. The set is intended for utility trailers, boat trailers, campers, RVs, trucks and other small towing applications where clear multi-function rear lighting is required.

How do these lights function as a combined tail, brake and turn unit?

Each lamp integrates multiple LEDs arranged to provide distinct signals for tail, stop/brake and turn functions. The pigtail wiring separates ground, tail and brake/turn circuits so the lamp connects to common trailer wiring harnesses. The left lamp also includes downward-facing LEDs to illuminate a license plate.

• Left lamp: 18 LEDs total — 12 front, 4 side marker, 4 white license plate LEDs.
• Right lamp: 15 LEDs total — 12 front, 4 side marker LEDs.
• Three-wire pigtail: white = ground, brown = tail, yellow/green = brake/turn.
• Functions: tail, stop, turn, side marker, reflectors, plus left license illumination.

How do I install these square LED trailer lights?

Installation is surface-mount and requires drilling or using the included studs to secure the housing to the trailer skin. Align the studs with a 2" on-center spacing, fasten with the supplied nuts and pads, then hardwire the pigtail into your trailer's wiring harness. Basic electrical knowledge or a service technician will help ensure a correct, weatherproof connection.

• Mounting studs: 2 inches on center, surface-mount design.
• Hardware included: mounting nuts and pads for immediate fitment.
• Wiring: hardwire pigtail to trailer harness; seal connections for moisture protection.
• Recommended tools: wrench for nuts, wire connectors, dielectric grease for terminals.

What makes these LEDs suitable for trailer use and visibility requirements?

The lights use multiple high-output diodes positioned for clear frontal and side visibility plus reflectors built into the lens. The combination of front-facing LEDs and side marker diodes increases the signaled area seen by other road users, while the reflexive elements help passive visibility when the lamps are unlit. The left lamp's dedicated license-plate LEDs provide task lighting without an extra fixture.

• High-visibility LED array for distinct brake and turn signaling.
• Side marker LEDs and integrated reflectors for lateral safety.
• Built-in license illumination on left unit avoids separate lamp installation.
• Designed for standard 12V DC trailer electrical systems.
