How do I replace the headlights on an Audi 80?

I have an Audi 80 and I need to replace the headlights. What steps should I follow to ensure a successful replacement?

First, make sure you have the right tools for the job, such as a socket wrench and a screwdriver. Next, open the hood of your car and locate the back of the headlight assembly. There should be a round, plastic cover that can be twisted off. Once removed, you will have access to the back of the headlight bulb. Carefully remove the old bulb and replace it with the new one, making sure not to touch the glass part of the new bulb. Finally, reattach the plastic cover and test the headlights to ensure they are working properly.
