I'm not too sure about the "legality" of it, but I can assure you that if their pattern is anything like the "HID" kits you're mentioning, then they'll probably be illegal as well. The best way to utilize these is to have them fitted in a projector housing so you're not blinding the shit out of everyone, but still much greater light output. With that being said, if they're similar to Silverstars, then you should be good.
