  • Patent number: 4227174
    Abstract: An automotive lamp flasher provides a visibly irregular series of flashes to indicate the existence of a distress situation. The flasher also provides a regular series of flashes as is done by existing flashers. Circuitry is provided to generate a nonuniform pulse train and repeatedly apply this pulse train to a lamp activation circuit. Broadly, a multiplexer with a plurality of input terminals is used, each having a logic level thereon. The multiplexer is sequentially stepped to provide an output representative of the sequence of logic levels on the input terminals. Preferred stepping means includes a timer for supplying a continuous sequence of uniformly spaced pulses, and a scaler responsive to these pulses for supplying a sequence of binary codes to the multiplexer.
