Abstract
A novel vehicle lighting control circuit for reducing the light intensity of a vehicle lighting element via pulse width modulation. A pulse width modulation adjuster is provided for producing a pulse width modulation control signal in order to operate the vehicle lighting element at a reduced light intensity. Such examples for use of the present invention include, but are not limited to, operation of: high beams at a low beam light intensity; daytime running lamps (DRLs); power balancing functions; and emergency lights.
