im just posting the topic as to get some solid clarity here.
if you want "clarity" posting a question that has a varying answer from state-to-state, in a forum with members across the globe won't get you that. go to a local state safety inspection station and ask, here in utah we have a hotline people can call.
the point of this post. to try to get some real evidence, like links to a gov website
so here you go, here are some "links to a gov website"
that won't help you anyway because vehicle safety laws vary from state-to-state
but you can just google your state's safety handbook as well
here's an example:
http://publicsafety.utah.gov/safetyinspections/safetyinspection.html
it can be seen on page 43 of this link:
http://publicsafety.utah.gov/safetyinspections/docs/X2009-2010 SI PLT ManuaL.pdf
but ultimately it says that only the "xenon" style hid lights are allowed, but they still must only project white light, still must be aimed correctly, and still must be d.o.t. approved (d.ot approvals only cover the headlight unit in its original "as approved" state)
SECTION 7 - LIGHTING
• Lenses that are patched, taped or covered with a temporary substance and lenses that have been equipped with any tinted covers MUST BE REJECTED.
• Lights must conform to manufacturer's specifications, Federal Motor Vehicle Safety Standards (FMVSS) and Utah State Laws.
• In 1996 the use of a clear cover for headlamps was approved for marketing in Utah (See NOTE in Headlamps).
•
Xenon bulbs are USDOT approved.

M. HEADLAMP AIMING REFERENCE
1. HEADLAMPS - HIGH AND LOW BEAMS
a. Vehicle must be tested on a level surface. Always adjust lights to a setting of 0-0 when using a mechanical aimer.
b. REJECT when:
1) Horizontal aim is more than:
a) 4 inches to the LEFT or
b) 4 inches to the RIGHT
2) Vertical aim is:
a) higher than 4 inches UP or
b) lower than 4 inches DOWN
3) Vehicles headlamps are lower than 22 inches or exceed 54 inches, measured from the ground to the center of the low beam.
*NOTE: If a mechanical aimer is used it should be used according to the manufacturer's instructions and must be calibrated to the slope of the floor on which the vehicle stands. Headlamp aiming by the screen method requires a level area in a darkened location, sufficient for the vehicle and an additional 25 feet from lamps to screen. As of January 1, 2009, all new stations are required to have an optical or screen headlight aimer. PLT Safety Inspection Manual, Effective January 1, 2009 51
