A top lighting solution, the 1-3/16 inch OD 3-diode bulkhead style LED light in amber is designed to deliver reliable marker or signal illumination in a small, easy-to-install format. Built with a chrome-plated bezel and a polycarbonate lens, it provides a clean finish while helping protect the internal LED components from road vibration and weather exposure. The 3-diode amber LED setup offers bright, efficient output and can function as a marker or turn signal light. It uses a grommet-style mount and standard bullet connectors, making installation straightforward in a 3/4-inch mounting hole setup. This unit is sold individually as a high-quality aftermarket replacement (not OEM) and is DOT compliant. It is also backed by a manufacturer warranty against defects in materials and workmanship. Commonly used on semi-trucks, trailers, and custom lighting setups, it is a practical option when space is limited but visibility and durability are still required.
