ABSTRACT:
A light control circuit includes a latching circuit actuated by a manually actuated switch to, in turn, activate a solid-state switch coupled to supply power to one or more lamps. The latching circuit is reset by a diode coupled to the door actuated switches such that in the event the interior lamp or lamps are manually operated and a door subsequently opened, the lamps will be extinguished upon the closing of the door regardless of the prior manual activation of the lamps.
