Headlights are essential safety components providing forward illumination for passenger cars and commercial vehicles. Positioned at the front of the vehicle, they enable drivers to see the road ahead during nighttime or low-visibility conditions. These assemblies typically incorporate a housing, reflector, lens, and bulb or LED light source. Modern headlights may also include features like daytime running lights (DRL) and integrated turn signals. Examples in this Electrical & Lighting > Lighting > Headlight category include Scania headlights (MPN 2674391, 2674384), Mercedes-Benz Truck headlight assemblies, and DT components (MPN 331185) as well as Volvo Truck headlight units. Proper headlight function and clarity are critical for safe operation and may be subject to vehicle inspection requirements.
