The TRUCK-LITE 10250Y is a 12-volt LED marker and clearance light designed for commercial and fleet vehicle applications. Built with a round lens and a 2-diode LED array, it delivers reliable visibility in a compact 2.5-inch length. The yellow lens meets standard marker and clearance light color requirements. Grommet-mount installation keeps the unit secure against vibration common in commercial truck environments. This light is a direct-install component typically handled by fleet technicians, truck equipment installers, and commercial vehicle service professionals.
This marker clearance light is suited for use on Class 3 through Class 8 trucks, trailers, and commercial vehicles where side or rear marker visibility is required. Its compact round-lens form factor and grommet-mount design make it appropriate for replacement work on existing marker light cutouts as well as new installation builds. The LED light source reduces power draw compared to incandescent alternatives and requires no bulb replacement over the service life of the diodes.
Designed as an OEM-style replacement marker and clearance light for commercial trucks, trailers, and fleet vehicles using standard grommet-mount round marker light housings.
Installation is typically performed by fleet service technicians or commercial vehicle electricians. Disconnect or isolate the vehicle circuit before removing the existing marker light to prevent shorts or unintended activation. The grommet-mount design seats into a pre-cut hole in the vehicle body; ensure the grommet is fully seated and the lens is secure before restoring power. Wire connections should comply with applicable SAE and FMVSS lighting standards for commercial vehicles.
