I've used this company's product for years in terms of OEM lamp replacement (good quality Taiwanese product). To my knowledge, it is USDOT approved. I'm not so sure about TUV approval on their US market items (if you care for that at all). Only thing is that it'll be a stripped lamp housing (no bulbs, HID ballast, wiring, etc)that's nice, thank you.
now presents itself to me, but the question is: matching accuracy?
