Amber 3 Light Marker Light Bar

An amber 3 light marker light bar is a device that is used to indicate the width and position of a vehicle or trailer that is more than 80 inches wide. It consists of three amber lights mounted on a base, usually white or black, that are spaced according to the DOT regulations. The lights are either incandescent, and they are connected to the vehicle’s electrical system by a wire or a plug. The light bar is usually installed on the rear of the vehicle or trailer, but it can also be used on the front or the sides.
