Partsam 4-Inch Round LED Trailer Lights Kit — 6 Lights, Red/White, Flange Mount, 12V

Overview

Meet Partsam's 4-Inch Round LED Trailer Lights kit, a versatile lighting solution for trucks, trailers, RVs, and service vehicles. The kit brings together six compact round fixtures: four red lights for stop, tail, turn, and parking signals, plus two white lights for reverse and back-up illumination. With recessed mounts and built-in flange rings, they deliver a clean, flush look when installed on flat surfaces.

Each red-lens fixture houses a 12-LED array, delivering bright, crisp signals while drawing less current than traditional incandescent lamps. The white-lens reverse lights also feature 12 LEDs for dependable back-up illumination in low-light conditions. The lights are designed for 12V DC systems and come hardwired with three wires — black (negative), red (brake/stop), and white (tail/running) — for straightforward wiring. A drilled installation requires a 3.8 in. inner hole or 4.2 in. outer hole for a snug, flush fit. The sealed construction helps resist moisture and exposure, making them suitable for outdoor use on trailers, trucks, and other vehicles.

Key benefits

• Waterproof and impact-resistant housing to withstand road and weather conditions.
• Low current draw and faster illumination compared with incandescent equivalents.
• Dedicated red and white LED arrays provide distinct, reliable signaling across functions.
• Universal 12V DC compatibility for a wide range of trucks, trailers, buses, RVs, and boats.

What you’ll typically use them for

• Trailer brake and tail lights with crisp red signals for safer towing.
• Turn indicators visible in daylight, even at a distance from the vehicle.
• Reverse and back-up lighting to illuminate the area behind the vehicle in dusk or fog.
• Vehicle upgrades on utility trailers, horse trailers, service vans, or pickup trucks for improved visibility.

Installation notes

These lights are designed for easy integration into 12V systems with a recessed flange mount for a clean appearance. The three-wire pigtail simplifies wiring: black for negative, red for brake/stop, white for tail/running. Quick-check that your drill hole matches the recommended inner/outer sizes to ensure a snug seal and long-lasting performance.
