Abstract : Motor vehicle drivers experience a big challenge from the bright beam falling directly on their eyes during their drive at night-times or fog. The driver feels an abrupt glare for a brief duration of time while driving at night. This results from the intensive beam of the headlight emitting from the vehicle that is driving towards him in the other lane. This glare results in a person becoming temporarily blind when they encounter road accidents during the dark of the night. So, need to avoid such kind of accidents. To solve this issue, developing an automatic headlight control method which uses light intensity sensor to control and adjust the headlight brightness when it perceives the light intensity from the headlight of the opposite vehicle. This method helps the drivers to avoid such problems. The proposed system consists of light sensor, PIC controller and relay switching unit. Here, the Light intensity detection sensor (3DU5C) is connected with a PIC18F45K22 controller to sense the environmental details and actuates the head light according to the opposite vehicle light intensity conditions.
