Guys, I had it wrong, I just talked to my buddy. Here's the story, the lights are from one of the original prototypes. But, they're not like the LS Koncepts lights. They are just the lid mounted lights. Originally, the reverse lights were placed inside those the lid mounted tails and bottom parts of those are clear and already molded for the reverse light bulbs. He's a trucker and picked them out of the discard can when he passed through Detroit knowing I had an LS. He says they had all kinds of prototype tails discarded at the time but they're most likely all gone now. He's going to bring them by this weekend. I'm still very curious as to what they look like and still think they'll be a nice novelty item. I'll post pictures as soon as I get them. I told him to let me know next time he makes a run through there. My guess is that they probably have other interesting prototype parts discarded for the more recent models of the LS. I don't know why they would discard them in the first place.
