Not really interested in what came in your off-the-lot driver / "hot rod", well, unless you had a choice of headlight types somehow, and and picked one type over the other. More interested in folks that upgraded their old halogen headlights -- what do you like and why? Me? Not a fan of HIDs because they always require hacking into the car's wiring, and then you have to find a clean place for that unsightly heat sink. I have seen some very well-done jobs, of course, but I've also seen a lot of hacked work, too, which makes me wonder why they changed in the first place. I like LEDs - easy, clean install, nice light. But that said, I'm not the king of headlights, so, lay it on me...
