The Stud-Mount Rectangular Amber Clearance Trailer Light can be used as a clearance or side marker light on your trailer. It increases visibility to notify other drivers of your trailer you are towing. It features an amber reflective lens and reduces the need for a separate reflector. The clearance light grounds through the mounting screw and has a single lead wire to connect to a DC power supply. Constructed from durable plastic corrosion-resistant housing to withstand extreme weather.
