Abstract
A turn-signal flasher circuit for automotive vehicles wherein a turn-signal switch controls one of two turn-signal lamp circuits, and in which a hazard warning switch controls both lamp circuits simultaneously. A pulse generator controls the frequency of the flashing light output of the lamps. A second pulse generator, having a mark-to-space ratio which is substantially less than the mark-to-space ratio of the first generator, is responsive to the hazard warning switch to control frequency of the simultaneous flashing of both lamp circuits during the hazard warning operation of the flasher circuit. Accordingly, battery drain is reduced and a longer period of hazard warning operation is attainable.
