Glare Stopper: The Automatic Car Headlight Management System
(2023-03-22) Abdullahi Daniyan, Samuel S. Ilupeju
The growing number of vehicles on roads calls for increased safety considerations, especially during night driving. A common issue is the misusage of high beam headlights, which can cause light glare for opposing drivers due to the high intensity beam a driver receives from oncoming vehicles. This is called the Troxler Effect. This is a safety critical issue given that the human eyes are very sensitive to light, and when eyes suddenly encounter high intensity light, one’s vision get temporarily affected and require some time to recover the vision. During this vision recovery window, the vehicle has covered some distance which could increase the likelihood of an accident occurring. To address this, we propose an automatic car headlight management system that adjusts a vehicle’s headlights based on light intensity of oncoming vehicles. The system utilizes an Arduino Uno microcontroller and an LDR sensor installed on the driver's side to detect light levels of at least 700 lumens. The microcontroller then sends a command to a relay, which switches the headlights from high beam to low beam. Results demonstrate effective performance of the proposed system in terms of achieving faster switching time and consuming lower power.
