This invention relates to a pair of flashing spectacles and in particular to one including a pair of spectacles, and an electrical device which has an external resistor for controlling frequency of the square waves generated by the oscillator, an on/off latch having an input connected with one and of a reset switch and an output connected with the oscillator and a counter, a decoder controller connected to output of the counter, an open drain driver connected with the decoder controller, a plurality of light emitting diodes connected with output of the open drain driver and a battery connected between output of the light emitting diodes and the other end of the reset switch whereby the light emitting diodes will emit light in turn when the reset switch is pressed once but will extinguish when the reset switch is further pressed.
