What does the automatic light mode mean?

Automatic light mode refers to the function where the car's headlights automatically turn on or off when the light-sensitive control system detects that the external light intensity is greater or less than a certain value. Below are the specific details about automatic headlights: 1. Working principle: The sensor consists of electronic components such as photoresistors, which send electronic signals to the ECU to control the turning on or off of the headlights, as well as the switching between high and low beams. When driving and encountering a sudden dark environment, the headlights will automatically turn on. They will automatically turn off when there is sufficient light. During nighttime driving, they will also automatically switch between high and low beams. 2. Function: Automatic headlights can turn on automatically when the owner forgets to turn them on, eliminating the need to manually switch them on when necessary. They can also automatically turn off based on the light intensity.
The automatic headlight mode is a quite practical feature, which means after setting the switch to auto, the vehicle's sensors will automatically control the headlights' on/off based on external light intensity. For example, they turn on when it gets dark or when entering a tunnel, and turn off at dawn. Having driven many cars, I've noticed this function relies on a small sensor on the windshield that detects the surrounding environment, saving you the hassle of manually operating the headlights. Especially during cloudy, rainy, or foggy seasons when visibility is poor, the auto-on lights provide an extra layer of safety, preventing fines or accidents due to forgetting to turn them on. However, it's important to keep the sensor clean and unobstructed to ensure its responsiveness.
