ABSTRACT:
A lighting and signaling device is provided which is capable of both lighting and signaling intermittent signals such as Morse code signals. The lighting and signaling device has a switch for selecting among an unlit mode, a continuous lighting mode, and an intermittent lighting mode; a clock circuit for oscillating at a single frequency in the intermittent lighting mode; a plurality of decade counters responsive to the clock circuit; and a driver for outputting periodic signals from outputs from the decade counters. The decade counters are arranged so as to output a series of dot and dash signals according to a predetermined program. The circuitry is housed within a portable flashlight.
