Abstract
Abstract In a vehicle, pulses are passed from a central pulse generator to accessories such as a heater clock, a turn indicator, and a flasher. The indicator and flasher control appropriate vehicle indicator lights with the pulses. Switches in the indicator and flasher enable a gate which passes the pulses from the generator through the indicator, or flasher, to the lamps.
