The pyroelectricity sensor which comprises a human body sensor(10) senses infrared ray emitting from the human body as a person approaches. The photo electric conversion element(A) senses the quantity of brightness around a parked car. These kinds of sensed signals are transferred to the human body sensing signal input terminal(set) of the control part(14). The control part(14) after the end processing of these two input signals, outputs the key hole lighting control signal thru the output terminal(OUT).
