An attachment for a cigarette lighter receptacle in a vehicle simulates the external shape, size, and appearance of a conventional vehicle cigarette light which is normally seated in the cigarette lighter receptacle. A control circuit, light source, smoke detector, and alarm are housed in the attachment. The attachment includes electrical contacts which are connected to the control circuit and which also, when the attachment is seated in the cigarette lighter receptacle, interconnect the control circuit with both the ground and electrical contact of the vehicle cigarette lighter receptacle.
