What does the auto light in a car mean?
1 Answers
The auto light on a car refers to the automatic headlights. Here is more information about auto lights: 1. The headlights will automatically turn on or off based on the light sensing system, enabling automatic activation/deactivation as well as automatic switching between high and low beams. When the light control is set to this position, the lights won't illuminate during daytime but will automatically activate at night, such as when driving through tunnels, on cloudy days, or in any dimly lit areas. 2. The working principle of auto lights is: Electronic components like photoresistors act as sensors to send electronic signals to the ECU, informing it whether to turn the headlights on/off, after which the ECU controls the headlight switch and high/low beam changes.
