ABSTRACT:
A signal light, which optionally may be combined with an ashtray base, having a quick-flip switch and a light conducting rod at the top so that when a patron of a restaurant or bar wishes immediate service the switch actuator is flipped and the light comes on to signal the desirability for service. The device comprises a tubular housing in which housing there is a spring for supporting batteries and the housing is mounted on a large circular base which may serve as an ashtray. The switch comprises a lightweight wire switch actuator which has small handles on both sides protruding from the top of the battery housing and a wire loop projection on the actuator which moves between electrical contact from the side of the battery housing to the small light bulb which is mounted on a non-conductor plastic collar fitting in which there is carried a rod of "LUCITE" (trademark) or other similar material.
