Now-a-days human beings have a tendency to transport in a faster pace which leads to greater street injuries. During night time motors typically tour in more velocity. When an coincidence happens in the course of night it is difficult for the rescue team to right away locate the place and shop the humans. This document gives a machine to robotically alternate between high and low beams with the aid of dimming the headlight of the different vehicles. Automatic collision prevention and detection is the device anticipated. It will become aware of a auto crash, and then ship the vital facts to the hospitals. This gadget substantially helps cars that have indulged in an accident in the search and rescue. The pace of the motors is one of the important reasons. If emergency offerings should achieve facts about accidents and attain them early, many lives can be saved. GPS has now end up a part of a vehicle framework. A GPS recipient is successful of checking the vehicle speed and recognizing mishaps dependent absolutely upon oversaw speed and sending an accident region to an Alert Service Center. We have put collectively an automated headlight dimmer prototype to stop such incidents. This adjusts the excessive beam routinely into the low beam, which reduces the depth of light by way of sensing the automobile approaching. It additionally eliminates the want for manual driver switching that is no longer constantly done. This paper talks about in element the building and blessings of this model.
