What does automatic headlights mean?

[LaBrady]

Automatic headlights are sensor-activated headlights that automatically turn on or off based on ambient light conditions. The function of automatic headlights is to serve as a light-sensing control system for the front headlights. The central intelligent control box determines changes in light brightness through a light sensor, thereby controlling the automatic activation or deactivation of the headlights to reduce safety hazards and improve driving safety. The principle of automatic headlights involves a photoresistor and electronic component sensors sending electronic signals to the ECU, instructing it whether to turn the headlights on or off or switch between high and low beams. Different car light usage scenarios: 1. Daytime running lights, also known as position lights, are used during rain or in dim lighting conditions; 2. Low beams are used on roads with street lighting; 3. High beams are used on roads without street lighting; 4. Turn signals should be activated in advance when the vehicle needs to make a turn.
