ABSTRACT:
A lighting system for over-the-road tractor-trailers or other large vehicles includes a plurality of lamps, mounted on a rear mud flap and directed downward and to the side, so as to cast a light pattern in an illuminated region on the road surface which is visible to the driver. Each lamp is mounted within a parabolic reflector and has a louver bolted on the bottom of the light to direct the light along a selected axis so as to effectively position the pattern at the most desirable location to allow the driver to see and control the rear of the truck. The driver is able to determine where the rear of the vehicle is by glancing at his side-mounted rear-view mirror and seeing the light pattern on the road surface. This facilitates maneuvering of the truck in tight spaces and in passing on the highway.
