RE: Mark VIII Headlights
Don't know what an HIR bulb is. I think he means HID, in which case you can't really put them in stock housings, and to find an HID setup for a gen 1, you're looking at a bit over a grand, probably.
Don't know the price of the stock housings off the top of my head, but they should only be a hundred bucks per side, give or take. Gen 2 housings are 200-250 a side, and they come with a $100+ HID bulb included. But they won't fit a gen 1.
