Because it was undriveable at night and I needed something ASAP so I traded it in. I didn't have the original head lights because they were damaged from hitting a deer on the road. Didn't want to be without my vehicle for a few weeks more (had been 3 months already). It sucks that I left them in there though.. they were SO bad ass. Definitely getting more retros for the Yukon in the future but first I need the esky roof rack, g5 tails, esky third brake light, and LTZ side mouldings... sadly all stuff I've bought in the past already :/
