ABSTRACT:
According to the present invention, a lighting control circuit is provided in which various logic gates, transistors and other smaller-scale circuit elements are combined. The circuit receives as inputs the control signals from the vehicle, including the left and right indicator signals, the brake signal and the tail light signal. Each of these signals is fed into a first bank of logic gates whose outputs are supplied to a second bank of logic gates, whose output is in turn supplied to two transistors, each connected to a separate single filament bulb, one for the left side of the vehicle and the other for the right side.
