How are the Audi A5 headlights controlled?

I've noticed that the headlights on my Audi A5 turn on and off automatically, even when I am not using the switch. How does this feature work?

The Audi A5 is equipped with automatic headlights that use a light sensor to detect ambient light levels. When it gets dark, the headlights will turn on automatically.

In addition to the light sensor, the Audi A5 also has a rain sensor that can activate the headlights when it detects rain. This feature helps to ensure visibility and safety while driving in inclement weather.

You can adjust the sensitivity of the automatic headlights in your Audi A5. Check your owner's manual for instructions on how to change this setting.
