Jamarco Square Red LED Trailer Tail Lights 2-Pack — Surface-Mount, 12V Combination Rear Lamps with Number Plate Light

Jamarco's 2-piece square red LED rear combination tail lights provide brake, turn, tail, side-marker, reflector and license-plate illumination in a single low-profile unit for 12V trailer systems.

These square LED trailer tail lights are a compact, surface-mount lighting solution built for trailers, RVs, boats and utility vehicles up to 80 inches wide. Each set includes left and right lamps with mounting nuts and pads, pre-wired pigtails, and a rugged red lens. The left lamp adds an integrated white LED to light the license plate, while both lamps deliver clear brake, turn and marker functions using energy-efficient LEDs.

How are these lights wired and installed on my trailer?

Installation is straightforward: each lamp uses a 3-wire pigtail that hardwires into your trailer harness. The mounting studs are spaced 2" on center, and these lights mount to the trailer surface, protruding slightly from the mount point.

• Wiring: white = ground, brown = tail light, yellow/green = brake and turn.
• Surface-mount design with included mounting nuts and pads for secure attachment.
• 2" stud spacing aligns with common trailer mounting holes.

What functions do the Jamarco square LEDs perform?

Each unit combines multiple rear lighting roles into one sealed lamp. Both left and right lamps perform as stop lights, turn signals, tail lights, rear reflectors and side markers; the left lamp also includes white LEDs for license-plate illumination.

• Stop and brake signaling for clear visibility under braking.
• Turn signal and tail lamp functions in one integrated housing.
• Side marker and rear reflector functions improve visibility from angles.
• Left lamp: additional downward-facing white LEDs to light the plate.

Are these lights compatible with my vehicle and 12V system?

Yes—these square LED tail lights are designed for standard 12V DC trailer electrical systems and are intended for towing vehicles with an overall width under 80 inches. They suit trailers, boats, RVs, small trucks, snowmobile trailers and utility trailers.

• 12V DC design matches most trailer wiring systems.
• Appropriate for trailers under 80" wide as a pair of rear combination lights.
• Durable sealed lens and multiple LEDs for high visibility in traffic and low light.

How do these lights improve visibility and durability?

The Jamarco lamps use multiple high-output diodes arranged for bright, even illumination and distinct signaling. The sealed, red lens protects the LEDs from road splash and weather while the combination of marker and reflector functions increases detection by other drivers.

• Left light: 18 LEDs total (12 front, 4 side marker, 4 white plate illumination).
• Right light: 15 LEDs total (12 front, 4 side marker) for strong rear signaling.
• Sealed construction helps resist moisture and road debris for long service life.
