A big rig light configured to improve visibility and safety for trucks, comprising a fairing panel light mounted to a rear edge of a fairing panel on a truck cab. The device includes a housing with a mounting plate, internal lens supports, and a plurality of light sources. The internal lens supports define multiple light segments, including a top light segment, a center light segment, and a bottom light segment. The light sources are independently controlled via a wiring harness electrically coupled to the truck's system. A lens covers the light sources, and the segments are configured to perform functions such as taillight, turn signal, brake light, and backup light. The device enhances safety by improving illumination and signaling visibility during various driving operations.
