Abstract
Abstract A music responsive light switching device comprising a music signal pickup which is connected to a control means which regulates the output of a power signal. The regulated power signal is applied to an electrical socket receptacle into which a conventional lamp is electrically plugged. The lamp can then be turned on and off in accordance with the characteristic rhythm of the music.
