Acquisition and analysis of light intensity and light beam length in passenger motor vehicles
The primary task of daytime running lights is for road users to perceive the presence of vehicles, as well as other road users, which is a basic prerequisite for safe traffic. The visibility of the vehicle, as well as of other road users, depends on the light intensity and light beam length of passenger vehicles. As the impact of daytime running lights on improving road safety has not been fully researched, in this paper the lights intensity and length of the light beam in passenger motor vehicles was measured and analysed. The research was done during the technical inspection of the vehicle (at the “Tachograph” technical inspection in Kragujevac). The results show that low beams are more efficient in illuminating the road compared to high beams, while there is no significant difference in light intensity between left and right vehicle headlights.
