Products Daytime Running Lights (DRL)



A daytime running light (DRL) is a forward lighting device that is intended to increase the visibility of a vehicle to other road users during daylight hours. The purpose of using daytime running lights is to reduce crashes by increasing the visual contrast between a vehicle and its background at times when headlights are not typically activated. The crash reduction potential of these lights is a function of their ability to attract attention with a sufficient level of luminance which improves the noticeability and detectability of vehicles in the central and peripheral fields of view. Improved vehicle visibility allows other road users to initiate evasive action in sufficient perception-reaction time and distance. Various configurations of DRLs have been implemented: highbeam headlights at reduced intensity, low-beam headlights at full or reduced power, front turn signal lights (steady burning until the turn signal control is activated), and dedicated lights with a defined luminous intensity and beam pattern.
