Truck-Lite 21275Y – 21 Series Yellow Rectangular 8-Diode LED Marker Clearance Light (Polycarbonate, 2-Screw Mount, Fit 'N Forget M/C, 12V)
Equip your commercial fleet, truck, or heavy-duty trailer with the exceptional reliability of the Truck-Lite 21275Y 21 Series Yellow Rectangular LED Marker Clearance Light.
