The combination includes a closed housing containing smoke heat sensing alarms. Also recessed flush within the housing is a light bulb socket for reception of a light bulb into a face of the housing. Protruding from an opposite face of the housing is an electrical connector, capable of screw-in attachment to a standard electrical outlet fixture. A switching device to turn the light on or off, forms of which include: push button, toggle switch, or pull chain, is installed within the closed housing such that the switch is operable externally of the housing. A second switching device, also operable externally of the housing activates and de-activates a self-contained battery power source to operate the smoke and heat sensor functions of the combination.
