To be quite honest, I'm not sure. I think it varies state to state but again, not sure. I've read it's not legal because you're not supposed to have HID's in headlights that weren't originally equipped with them. But then again, when you retrofit, you're adding the projector which is allowing the HID to be used properly? If that makes any sense. I dunno lol.
Think of it this way... I've read 1 out of like every 30 cars in California have P&P kits without a proper retrofit. I'm sure if they can get away with it, we'll be fine with our retrofits .
This time, they have a s*** ton more projectors. So if any of you are interested in doing a retrofit, now is the time to get good deals!!!!!!!!! I'm actually tempted to pick up another set of Mini H1's because that's a great deal.
