Why is my Audi 80's dashboard lights flickering?

I noticed that the dashboard lights of my Audi 80 are flickering on and off randomly. What could be causing this issue and how can I fix it?

This could be due to a loose connection in the wiring of your dashboard lights. Try checking the connections and tightening them if necessary.

Another possibility is a faulty headlight switch. If cleaning and tightening the connections doesn't work, consider replacing the switch.
