Abstract: Control circuit for shifting a compartment light between an illuminating condition and a non-illuminating condition for use in a vehicle having a door, a manually actuated door switch and a manually actuated control switch generally in combination with the ignition switch of the vehicle. The control circuit provides means for causing the compartment light to remain illuminated for a preselected time delay after the vehicle door has been closed and a second means for providing a different time delay holding the compartment light illuminated for a time after the control switch has been turned off.

Abstract: A control circuit for controlling the compartment or dome light of a vehicle whereby the dome light remains on after one of the door handle buttons has been depressed. This circuit includes means for retaining a fixed timing function, irrespective of the time the door is opened. Also, the circuit includes means for deactivating the operating circuit during steady state conditions whereby the amount of energy dissipated by the circuit is minimized.
