ABSTRACT:
The light-emitting electronic jewelry of the invention includes a base item of jewelry having a light emitter and at least one light sensor mounted thereon and connected in an electrical circuit with other circuit elements which coact to intermittently interrupt the emission of light from the light emitter in response to changes in ambient light intensity sensed by the light sensor. Preferably a pair of light sensors are connected in series with the output to the light producing circuit taken between them.
