Abstract
An electrical control circuit for an automotive lamp module having an integrated ON/OFF switch to activate and deactivate the driver circuit associated with the lamp such that the driver circuit is only turned on when either the primary ON/OFF switch or a remote, door-ajar switch is closed. A microprocessor is used to respond to low-level current conditions indicative of a closed switch. A timer turns the driver OFF after a predetermined duration of continuous operation.
