Abstract
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.
