A motor vehicle lighting system includes a master controller, a smart light, and a hot bus. The master controller is electrically couplable to a power supply and is adapted to receive an input signal corresponding to a left turn signal, a right turn signal, a run signal, or a brake signal. The master controller also includes a digital command signal output that is produced in response to the input signal. The smart light includes a light controller and a plurality of light emitting diodes (LED's). The light controller is adapted to control the LED's in response to the command signal. The hot bus electrically couples the master controller to the smart light. Power and the command signal are provided to the smart light over the hot bus.

A system according to claim 2, wherein the upwardly extending peripheral wall comprises front and side sections, characterized by said mounting member being disposed on the top edge of the front section and provided with a generally horizontally disposed support plate, and said positioning mechanism being mounted on and manually adjustable both rotatably and linearly relative to said support plate to permit selective positioning of said contact member at said predetermined distance. 4. A system according to claim 3, characterized by said positioning mechanism comprising a first element mounted for limited rotary movement relative to said support plate, a second element mounted for limited linear movement relative to said first element and said support plate, and manually operable restraining means for selectively restraining said first and second elements against movement relative to each other and to said support plate after said contact member has been moved by said positioning mechanism to said predetermined distance. 5. A system according to claim 4, wherein said positioning mechanism is further characterized by said first element being pivoted on said support plate for limited rotation thereon, said second element being slidable on said first element for limited linear movement thereon, said first element being rotatable relative to said support plate and said second element being linearly slidable on said first element to permit manual selective placement of said contact member at said predetermined distance. 6. A system according to claim 5, wherein said support plate is provided with a pair of spaced generally parallel dependent legs straddling the top edge of the front wall section, and manually operable means carried by one of said legs for removably clamping said support plate at a manually selectable height on said front wall section. 7. A system according to claim 6, characterized by said contact member being mounted on said second element for limited pivotal movement thereon, said switch being mounted on said second element and provided with a operating member adapted to move with said contact member between a position in which said switch is inoperative and a position in which said switch is operative, and resilient means normally biasing said contact member to its generally vertical position and said operating member to its inoperative position. 8. A system according to claim 7, wherein the truck provides an electrical power source, characterized by said warning device comprising transducer means for converting an electrical signal into a humanly discernible event, an electrical circuit removably connected to the power source and extending between said switch and said transducer means, said contact member and said operating member being moved to close said switch in response to contact between said contact member and the forward extension upon rotary movement of such forward extension beyond said predetermined distance during a turning maneuver of the truck, said closure connecting said transducer means to said power source to activate said transducer to create said discernible event. 9. A system according to claim 1, wherein the truck has a bed provided with an upwardly extending peripheral wall having front and side sections, characterized by said warning means being positioned within the cab and said alarm means comprising a pair of alarm assemblies spaced apart on the front wall section, each said alarm assembly being characterized by said mounting means compr
