Smart Headlight Dimmer using Raspberry Pi

Abstract: Driving in low-lighting conditions can raise several challenges that may affect your safety at night. Due to darkness, low visibility is the most frequent issue that drivers have at night. It will be difficult to see obstacles, pedestrians and vehicles on the road and another important problem is glare of Oncoming headlights from high intensity beams of xenon or LED headlights of the front facing vehicles. This will lead to temporary blindness for the drivers. In this situation driving the vehicle is a challenging task. It will be difficult to drive with the traditional headlights in such conditions. It poses a serious threat, and many accidents are caused by temporary blindness. According to the Indian statistics, more than 60% of accidents occur during night time and the main reasons behind those accidents is headlights problems. The abrupt brightness experienced by the travellers is known as the Troxler Effect. However, there is an option in every vehicle weather to keep the headlight either high or low when the vehicle is coming from the front side and this is called as upper and dipper system. Some of the drivers do follow this system as the car approaches them at night but a lot of them do not. Due to which it led to the problem of lack of visibility on the road due to constant glare of the headlights. Heavy vehicle’s (like trucks and buses) have extremely powerful headlights which produce very high intensity lights that in turn result in fatal accidents. Truck and bus drivers will ignore to reduce the headlight intensity when small vehicles are approaching them. As we analyse the current highway situation, most of the goods and passenger transportation occur during night. In lots of time These vehicles jeopardise the safety of other people. There is no such system available which can automatically high and low beam those headlights of heavy vehicles and even high beams of small vehicles. To resolve this problem, The System should be developed so that when a car or bike approaches another vehicle then there should be automatic change in the upper and dipper mode of the lights and reduce the light intensity. So that accidents due to headlights can be reduced.
