Not quite sure about the last option though.



You shouldn't use HID in lamp housings designed for halogens; this will just cause a lot of angry people and possibly a ticket or two. HID bulbs should be used in a proper projector housing in order to stay within DOT regs. High beams are one thing since you won't be using them for regular on road driving [i.e. since you turn them off when someone is in front of you and you'd turn them off when a vehicle is passing in the opposite direction]. Using HIDs in a halogen designed lamp housing [designated by usually having a "H" marking at the top of the glass] will cause heavy glare, halos, and artifacting; this causes other people on the road to have issues with their night vision.

Projector lamps have a horizontal cut off


Where as halogens typically have more of a spot light patterned beam.
