Upgrade your commercial vehicle or trailer's visibility with the industry-trusted Truck-Lite 18090Y 18 Series LED Marker Clearance Light Kit. Designed specifically for heavy-duty vocational trucks, trailers, and utility vehicles, this 2" x 5" rectangular marker light delivers robust safety lighting that stands up to the harshest road elements.

Built around high-performance solid-state electronics, the Truck-Lite 18090Y features a filament-free, 3-diode design that makes it intensely resistant to shock, road vibrations, and impact. Unlike traditional incandescent lamps that burn out easily, this sealed LED assembly boasts an impressive 36-month manufacturer warranty. Its specialized acrylic Diamond Shell® lens is both scratch- and fade-resistant, featuring an integrated reflectorized pattern that optimizes light output while keeping you fully legal on the highway.

Installation is engineered to be as straightforward as possible. The 18090Y model features a surface-style, 2-screw mount designed to map perfectly onto standard heavy-duty fleet configurations. The hardwired connection includes two 4-inch blunt-cut wires, giving technicians a reliable, tight splice that blocks out water and road salt. Whether you are running a single rig or managing a large commercial fleet, this 12V amber/yellow clearance light ensures maximum side and rear visibility.

Note: Recommended for horizontal applications requiring a 0–35 degree rollback. Not suitable for applications with PC clearance requirements.
