ABSTRACT:
A visual signaling system is provided incorporating strobe light means which emits flashes of light at a constant rate, as distinguished from a random rate, despite variations in input voltage applied to the system. The system enables predetermined signals to be perceived by persons in high decibel areas or by heating impaired persons, and multiple signaling units may be incorporated in a multistation system whereby the strobe lights in each of the signaling units all flash simultaneously at a synchronized rate, as distinguished from independently or at random rates.
