Abstract
A portable light for emergency illumination which is activated in response to the sound emitted by a smoke alarm device, which light has an efficient and reliable battery conserving circuit. The present light includes a switch interconnecting a battery and a light bulb for selectively activating the light bulb and a circuit interconnecting a microphone and the switch for selectively activating the switch in response to a smoke alarm signal. A strobe circuit interconnects the source of power and the circuit for periodically activating the circuit which, therefore, draws power for only a small fraction of the time.
