ABSTRACT:
A single-wire system for controlling electrical devices and multiple lights such as warning and signal lights for buses and other vehicles. The system includes a transmitter at a forward end of the vehicle and a receiver at the rear, a power supply and a signal lead. The transmitter operates in a "parallel in"-"serial out" mode and converts simultaneously-received input signals into a sequential or serial output format for transmission, on a single wire, to a "serial-in"-"parallel-out" receiver where the signals are decoded to provide rapid-pulse command data. These data bits are then directed to appropriate stations, including lamps, for energization thereof as warning and signal elements.
