Abstract
A method for automatically controlling headlamps in response to windshield wiper controls is provided. A microcontroller senses the voltage levels of signals from a windshield wiper switch and a headlamp switch. If the microcontroller senses that the vehicle operator has turned on the windshield wiper switch, the microcontroller turns on the headlamps of a vehicle unless the windshield wipers are in intermittent mode or the operator of the vehicle has turned off the headlamps within a predetermined period of time.
