It says it's not DOT approved. We don't do bike inspections in AR. Are there states that could check for DOT approval?

I may be wrong, but unless you find a true aftermarket housing/projector that's DOT approved for HID/LED bulbs, anything but your standard H7 halogen is going to be for "off road only" use.
At least here in central Iowa, unless you give the police a reason to pull you over, it's highly unlikely any reasonable HID/LED setup (color temp/output/correct aiming) will get you stopped just for it. Same can be said for license plate lights, they're a giveaway for probable cause if you're acting suspicious or stupid, for a traffic stop.
I know I didn't really answer your question directly, but all I've ever heard of stateside is some states doing emissions testing.
