Replacing separate high beam halogens with HID I can understand, but putting a HID into a low beam reflector designed for halogen is another story. There is simply no control over light scatter, and it goes in all directions - the low beam cut-off is gone, non-existant.
The main reason people don't flash at HID lowbeams is because you soon learn that squinting and trying to see enough of the road to safely get past the oncoming vehicle is far preferable to having them turn their HID highbeam on you.
There's no legal way to go HID unless you can also make your lights self-level and fit some sort of washer system, but if you choose to overlook this, you can do a projector retrofit that gives a proper low beam cut-off and no scattered light, plus a great high beam:
I plan to fit a set of these. I got them from "Mick's HID Projector Retrofits", a vendor on Patrol4x4.com - I have no affiliation but think his service and products are top shelf. These kits just about make driving lights redundant.
