Uriah Products UL903000 is a replacement clearance marker light for trailers. Measuring 4" x 2" x 1-1/8", this rectangular, LED amber light includes a double bulls eye style lens and has a single-wire connection. Trailers should never be towed if their lights are not fully functional, so if your old trailer marker light has burnt out, cracked or faded, replace it with this part and get back on the road. It includes a white mounting base and the mounting holes are 3" apart for easy installation.
