It’s designed to be mounted through a 3/4-inch hole with a grommet and wired directly (hardwired with bullet connectors) on trucks and trailers. Its single diode provides a bright light that exceeds legal output requirements for marker and clearance lamps while drawing very little current. Replace it when an old incandescent or damaged marker light fails, dims, cracks, or to upgrade to a long-life, fully sealed LED unit that resists moisture and corrosion.
