How to Change the Brake Bulbs in a 2006 Audi A4

1. Open your 2006 Audi A4's trunk.
2. Remove the screw behind the taillight (inside the trunk) using a Phillips-head screwdriver or an 8mm socket.
3. Tap on the taillight from the inside of the trunk with the palm of your hand until the taillight comes off.
4. Unclip both of the back clips on the back of the taillight with your hand, then slide the taillight off the bulbs.
5. Unscrew the old bulb from its socket and screw the new bulb in.
6. Slide the taillight over the bulbs and clip the two black clips on the back of the light back into place.
7. Place the taillight back on the car and secure it in place using the screw you removed earlier.
