DAYTIME RUNNING LIGHT. A daytime running light (DRL) is a component of a vehicle’s exterior lighting system designed to improve the visibility of the vehicle during daylight conditions. Daytime running lights help other road users notice the vehicle more easily while it is in motion, thereby improving overall road safety. The primary function of DRLs is to increase vehicle visibility without the need to use full headlight illumination during the day. Compared to low beam headlights, daytime running lights consume less electrical power and produce a controlled level of brightness that is sufficient for daytime visibility while reducing the load on the vehicle’s electrical system. DRLs can be designed as standalone lighting modules integrated into the front bumper, grille or headlamp assembly of the vehicle. Modern daytime running lights commonly use LED technology, which provides high brightness, energy efficiency and long service life. The design of these lighting units ensures resistance to moisture, dust, vibration and temperature fluctuations, allowing reliable operation in various driving conditions. In many countries the use of daytime running lights is mandatory as part of modern vehicle safety standards. The catalog includes daytime running lights of various designs intended for installation on passenger cars, SUVs and commercial vehicles.
