Uriah Products UL168100 is a replacement LED clearance marker light for trailers. Measuring 2-1/2" x 3/4", this amber, rectangular light is housed in a chrome bezel and easily installs on your trailer. 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.
