and this was something I was concerned about as well. Especially since it was a used kit. I'd imagine with all the NHTSA banning the re-based 900x bulbs will become a bit more difficult to find. - glad you were able to get ahold of a set. You are replacing both of them aren't you? I've read alot of people who replace only one bulb find the colours don't match.
Honestly I'm more concerned with the issue of getting pulled over and harassed by the cops for having them. I haven't actually driven the car with them yet (it'll be a month or two before I do) but they are REALLY f'ing bright. Almost too bright. Hopefully I'll be able to aim them effectively. Have you ever been harassed by the cops with your phillips kit?
