What does AUTO mean for car lights?

[VeraFitz]

Car light AUTO refers to a system that automatically controls the turning on and off of lights based on environmental conditions, also known as automatic headlights, which is a system installed by car manufacturers for user convenience. When the car light is set to this position, the lights will automatically turn on when passing through tunnels or in dimly lit areas; when exiting the tunnel or when there is sufficient light, the lights will automatically turn off. Car headlights, also known as car front lights or car LED daytime running lights, serve as the eyes of the car. They not only relate to the external image of a car owner but are also closely linked to safe driving at night or under bad weather conditions. Car headlights are categorized into halogen lamps, xenon lamps, LED lamps, laser lamps, etc.
