Why do the headlights flicker on my Audi 80?

I've noticed that occasionally, the headlights on my Audi 80 will flicker and occasionally, one headlight will turn off completely. What could be causing this issue and how can it be resolved?

This could be a sign of a failing alternator. It's important to have it checked and replaced if necessary, to prevent further electrical issues.

I had a similar issue with my Audi 80 and it turned out to be a loose connection in the headlight wiring. Make sure to check all the connections and secure them properly.
