The TowSmart Clearance Light can be used as a clearance or side marker light on your trailer or vehicle. It increases visibility to notify other drivers of your trailer or vehicle. The clearance light features durable plastic housing with built-in drain holes to prevent corrosion and withstand harsh weather conditions. It provides a snap-on reflective lens that is easy to use. This allows easy removal of the lens to install the light, replace the bulb or replace the lens. The clearance light grounds through the mounting screw and has a single lead wire to connect to a DC power supply. The clearance lights are available in red and amber.
