Yea, I remember when I did mine, I didn't have time to put everything back in before my wif ewent to work that night and I forgot all about the 3rd brake light. Let's just say, when she hit the brakes, it lite the whole car up and about blinded her in the rearview. She won't too happy, but I got a good laugh. It's not that bad to do though, should only take you about 10 or 15 minutes to get to them.
