ABSTRACT:
A flashing and sound generating lamp that repeats on-off operation and generates a characteristic audible sound when an electric current is supplied to the lamp. The lamp comprises a thermally bendable member connected in series or in parallel with the lamp filament to effect on-off energization of the filament as a result of the bending of the member due to the presence and absence of radiant heat from the filament, and a concavity is prefabricated into the thermally bendable member to cause the member to bend with a snap action thereby to generate a characteristic sound each time the lamp is turned on and off.
