ABSTRACT:
A simple, inoffensive, and economic device is provided for signaling to get the attention of a waiter or waitress in a restaurant. A housing having a flat top and bottom holds one or more light emitters, preferably a number of light emitting diodes. A battery in the housing powers the lights through a gravity actuated switch and an intermittent flashing circuit. One flat face of the device is attached to the bottom of a can or bottle. When upright, the container rests on the device, and the lights are off. When the container is inverted to signal for service, the switch powers the emitters, which flash intermittently. The device may include a mechanism to stabilize the container in the inverted position.
