Hopkins Towing Solutions LED 3/4" Round Clearance Side Marker, Amber meets DOT (USA FMVSS108 and Canada CMVSS) safety requirements for combination clearance lighting for trailers. Its small shape is compared to the size of a penny, hence the nickname "penny light." The clearance marker is PC rated meaning that it can be seen 90 degrees off from its center, helping to make your trailer more visible from all angles. The 12V marker light contains 1 high-output LED for exceptional brightness and performance. The life of a LED light far exceeds traditional incandescent lights and draws significantly less power. The penny light can be used as a side marker light and can also be used as ID lights(3 required), utility, step well, or cabinet lights. The penny lights come with a rubber grommet and easily install into any 3/4" opening.  The LED design is epoxy coated and sealed making them water resistant.
