How to change a burnt-out headlight bulb in an Audi 80?

I recently noticed that one of my headlights is not working in my Audi 80. I suspect it may be a burnt-out bulb, but I am not sure how to change it. Can someone provide instructions on how to replace the headlight bulb?

First, locate the back of the headlight assembly on the affected side. Depending on the model year of your Audi 80, you may need to remove a cover or access panel. Then, twist the headlight bulb counterclockwise to remove it from the assembly. Replace it with a new bulb and twist it clockwise to secure it.
