Design of Light-Sensing Automatic Headlamps and Taillamps for Automobiles

This paper demonstrates a model of Light-Sensing Automatic Headlamps and Taillamps for Automobiles. Light-dependent resistor and other basic components are used for the basic functioning of the model. For avoiding the human eye effects, a prototype model has been developed for dimming down the bright headlight of the vehicles when opposite side vehicles are coming. Dimmer is a simple electronic circuit that consists of light sensors (LDR) and control circuit. It senses the switches headlight and function according to the condition applied. This circuit switches convert light intensity from high beam to low beam automatically and also minimized the glare effect by sensing the light intensity value and also eliminate the manual switches which are in control of diver. Drivers are not able to always handle this system while this designed circuit will do perfectly whenever is required and also help the driver to drive the vehicles on the road in fast speed without any barrier. The proposed circuit is designed and tested and it is working and sensing up to a distance of 147 m.
