The bulbs in the tail lights corrode in place due to excess road grime (salt, sand, etc. ) being splashed up on them. This causes them to burn out prematurely and removal is impossible due to the corrosion of the bulb into the socket. This results in having to replace the entire wiring harness. According to my local GMC dealership (west herr), this is a common problem that gm isn't covering. So, I had to pay for a new wiring harness out of pocket in order to replace one of the tail light bulbs.
