To remove the Third brake light start by gently pullin down on the trunk carpet near the plastic plugs. They will pull right out. After you have the carpet removed you are ready to remove the Brake light. There are 2 10mm bolts that hold it in. Remove these bolts. After the bolts are removed. there are 2 little push clips that are still holding the light in place, push these inwards as you pull down on the housing. And it should be out.
