Partsam 20-Pack 3.8-inch Amber/Red LED Side Marker Lights — DOT Approved, Waterproof for Trailers, Trucks, RVs

Overview

Upgrade your vehicle’s visibility with the Partsam 3.8-inch amber and red LED marker lights. These compact lights deliver a crisp glow that helps other motorists spot your trailer, truck, or RV from a distance. Built with performance in mind, they combine bright illumination with a rugged, weather-ready design that stands up to day-to-day use and varied road conditions.

Bright, reliable visibility

Each marker light houses 6 high‑intensity LEDs to create a steady, evenly lit line along the body of your vehicle. Amber tones emphasize sides and approaches, while red signals reinforce rear and turning cues. DOT approval ensures the lights meet established standards for trailer and vehicle lighting, giving you confidence without guessing about compliance.

Easy installation and waterproof mounting

The lights feature a low-profile housing and generous ground/power wire lengths for flexible routing. Black is negative and red is positive for straightforward wiring. A peel‑and‑stick gasket on the back enables waterproof mounting, reducing the need for additional sealant while keeping the surface tidy and protected.

Versatile, universal fit

Designed for 12V systems, these markers work across a broad range of vehicles—including trucks, trailers, boat trailers, RVs, campers, motorcycles, and more. Use them as side markers, indicators, clearance lights, turn signals, rear lights, running lights, or decorative accents to enhance both safety and style.
