Abstract
A decorative light flashing apparatus employs a mass-damped dynamic microphone which preferentially responds to impulse-type sounds to trigger a timing circuit. The timing circuit produces pulses in response to the impulse-type sounds which drive a commutating circuit for sequentially illuminating a plurality of light sources in time to the impulse-type sounds.
