How do I change the headlight bulbs in my Audi A1?

I have noticed that my headlights are not as bright as they used to be and I want to replace the bulbs myself. Can someone guide me through the steps to change the bulbs in an Audi A1?

To change the headlight bulbs in an Audi A1, first open the hood and locate the back of the headlight assembly. On the back, you will see a round cap that can be twisted off. Remove the cap and then twist the old bulb counter-clockwise to remove it. Then, insert the new bulb in the same way and twist it clockwise to secure it. Make sure to test the new bulb before closing the cap.
