This paper proposes an efficient method to control the headlight intensity of the vehicle using ambient light sensor (ALS) based on phototransistor with the principle of pulse width modulation. The main responsibility of this automatic headlight control is to control the intensity of the headlight based on the ambient light. The intensity of the headlight will be low when the ambient light intensity is high and vice versa.
