last I heard (which was awhile ago) makers had to come up with something new, because hid was too bright and caused accidents, by blinding other drivers.
(Especially those god damn suv's that have the headlights over 3.5' off the road)
edit**
I wanted to add an image that I found

Both car's are HID equipped.
The car on the left is oem hid, w/ proper shielding and a lens
The car on the right, is a fuck-tard that has nothing but a bulb.
Want more?
