Bhavesh Anant Chavan

Abstract: Nowadays, there are very high intensity LEDs or Halogen lights used in headlight of vehicles. These high intense lights fall on eyes of opposite driver and it creates temporary blindness in his eyes and this situation becomes responsible for the major road accidents. To avoid such accidents to some extent, I have made automatic switching of upper and dipper lights of vehicle which will reduce the possibilities of accidents by their operation in response to with Light dependent resistor (LDR) as a light sensor. Whenever there will be another vehicle coming towards it from front side, LDR will respond to the headlight and upper headlight will turn off and dipper will turn on for specific period of time until that another vehicle passes away.
