Car lights can be divided into exterior and interior lights. Exterior lighting is used on-road illumination, safety and comfort and has a special significance as a design feature. Car headlamps are used to illuminate the road in darkness and poor visibility, for example in fog. Displaying the driving behavior by turn indicators, brake light and reversing light is an important safety function. The use of the parking light and daytime running lights also increases the traffic safety of all transport users, as vehicles are better seen. A further feature is the driving comfort, which increases significantly with asymmetrical low beam and adaptive high-beam assistant. However, interior lights increase the comfort of the occupants. Vehicle lights are usually combined in a single unit and mounted on multi-lane vehicles on the front or in the rear. The main components are housings, reflectors and the outer pane. The operating levels of vehicle lights depend on the driving situation and the visual conditions: parking light, low beam, high beam. The light sources are distinguished in halogen, Xeneon and LED. Parabolic mirrors or clear-glass headlamps with free-form reflectors or projection lights are typical variants.
