A flashing light cable for electrically connecting a musical instrument or a microphone to an amplifier or to a sound system, for use by an entertainer to enhance the visual appeal of a stage performance. The cable comprises two jacks having an elongated cable portion extending therebetween. The cable portion comprises a conductive wire in electrical communication with each of the jacks, and a plastic insulation that sheathes the conductive wire. The plastic insulation has a plurality of spatially separated flashing light bulbs partially embedded therein. When the cable is used to electrically connect two pieces of electrical equipment, and when the equipment is selectively activated, current flows through the cable, thereby causing the light bulbs to be selectively and intermittently illuminated, and enhancing the visual appeal of a stage performance by the entertainer.
