How do I replace the headlight bulb on an Audi 80?

I noticed that one of my headlight bulbs is out on my Audi 80. How do I replace it safely and effectively?

First, make sure to turn off your Audi 80's engine and let it cool down before attempting to replace the headlight bulb. Then, locate the headlight bulb housing and remove the cover. Be careful not to touch the bulb directly with your fingers, as the oils from your skin can damage it. Unscrew the old bulb and insert the new one, making sure it is securely in place. Finally, replace the cover and turn on your engine to test the new bulb.
