How do I replace the turn signal bulb in an Audi A4?

I can't figure out how to access the turn signal bulb in my Audi A4. The manual isn't very helpful. Can someone walk me through the steps?

To replace the turn signal bulb in an Audi A4, you'll need to remove the headlight assembly. First, disconnect the negative battery cable. Then, remove the screws or fasteners holding the assembly in place. Once the assembly is loose, you can access and replace the bulb.
