Automatic Dimmer System

The Headlights of vehicles pose a great danger during night driving. The drivers experience a sudden glare for a short period of time which causes a temporary blindness to a person resulting in road accidents during the night.

This is caused due to the high intensity of headlight from the other vehicle coming towards him from the opposite direction. To avoid such incidents, we have fabricated a circuit of automatic dimmer device in which light falling over the light dependent resistor from the headlight of vehicle coming from the front automatically reduces the intensity of light by sensing it.
