Well.....Are you wanting to change out a bulb or the entire brake light assembley? For bulb only replacement>Open the trunk,You will see a small service pannel on the left and right. Lift the selected side pannel from the bottom straight upward. There is two tabs on the bottom you can work out with your finger. You can now service the bulbs. If it's necessary to continue on replacing the entire brake light housing,you need a #8 socket or wrench to remove 3 nuts. Then the entire housing will pull straight outward. Squirrel Crusher
