How to replace headlights in an Audi A6?

I'm having difficulty replacing the headlights on my Audi A6. Are there any specific steps or tools I should know about?

First, you'll need a set of replacement headlights and a screwdriver. Begin by opening the hood and locating the back of the headlight assembly. Carefully unscrew any bolts holding it in place and gently remove the old headlight. Then, place the new headlight into the assembly and secure it back in place using the bolts. Repeat for the other headlight if necessary.
