How can I change the headlight bulbs on my Audi A4?

I need to replace the headlight bulbs on my Audi A4, but I'm not sure how to do it. Can someone provide step-by-step instructions to help me out?

First, open the hood of your Audi A4 and locate the headlight assembly on the side you want to change. Then, unplug the electrical connector from the back of the assembly.

Next, twist the old bulb counterclockwise to remove it from the assembly. Be careful not to touch the glass part of the new bulb as the oils from your skin can cause it to overheat and fail prematurely.

Once the old bulb is removed, insert the new bulb into the assembly and twist it clockwise to secure it in place. Then, reconnect the electrical connector and test the new bulb to make sure it is working properly.
