Abstract: The light flashing apparatus of the present invention is a four-button control switch in conjunction with an electronic circuit which is installed within an existing light switch junction box and replaces conventional switches. In addition to the two conventional on and off modes of a light switch, the apparatus allows for two different flashing modes; slow and fast flashing of the same light.
