What does the auto light button in the car mean?

[NicoleLee]

The auto light button in the car refers to the automatic headlights, which do not require manual operation and can automatically turn on or off, as well as automatically switch between high and low beams. The automatic headlights are controlled by a light sensor installed in the car. When the light becomes dim, the headlights automatically turn on, and when the light becomes bright, the headlights automatically turn off. They can also automatically switch between high and low beams during encounters with other vehicles. Automatic headlights reduce the driver's operation and are a convenient and practical configuration. Some car models are not only equipped with automatic headlights but also features such as adaptive headlights and automatic headlight height adjustment. Adaptive headlights can reduce blind spots when turning, improving nighttime driving safety.
