ABSTRACT:
A motor vehicle headlamp control system wherein a two-position solenoid operated ratcheting switch conducts current from the storage battery to the headlamps. The position of the switch controls the energization of the headlamps and momentary energization of the solenoid changes the position of the switch. The driver may manually energize the solenoid to control the headlamps and the switch is automatically shifted to a position to deenergize the headlamps when the vehicle ignition key is shifted to an "off" position. Automatic turn-on and delayed turn-off functions are also provided.
