How do you change a brake light in a 2002 Aurora?

You have to do it from inside the trunk. Remove the plastic screws that hold the cargo net in (they should just screw out). Then, pull the plastic trim that was under the plastic screws out to expose the studs that hold the tail lights in (there should be 2-3 studs). Remove any screws if there are any present and the entire taillight assembly should be loose enough to remove. Pull the assembly away from the car, be careful not to short out the cords, and remove the bulbs just like you would any bulb.
