ABSTRACT:
An improved system for lighting an automobile central rear window warning, or "third" red light, employs an unlimited linear motion switch coupled to the accelerator-carburetor linkage and a logic unit coupled to the switch and the electric lines for the conventional brake, turn signal and back-up signal maps, and, optionally, to a clutch switch, so as to light the "third" warning lamp. The linear switch unit receives a rod in its housing, which rod is coupled to the carburetor or accelerator linkage. The rod rolls a spring-mounted roller to an off center position, thus activating or deactivating a pair of contacts upon any movement of the rod beyond a small increment. The linear switch rapidly responds to any reversing movement of the accelerator pedal, no matter what absolute position the rod is in at the time. The linear switch, in conjunction with the logic unit, serves to maintain the rear "third" red light "on" for all occasion when the automobile is being operated or is commencing to be operated in a manner which could be a danger to another vehicle approaching it from the rear. Thus, it lights in all normal conditions, plus reverse or turn signaling which may flash or hold steady depending on the positioning of the accelerator pedal. With a slight release of the accelerator pedal, any activation is maintained until the pedal is again depressed.
