I found a lid that fitted very nicely today so I bought it. Now it's the beginning of summer soon and I want a tinted visor for it. So the questions are: what's actually legal and does it really matter? What does Iridium actually mean and how does it differ from mirror? Suggestions on where to purchase would be nice also. I've found a couple of places from googling but none of them seem to offer much info about their visors. I want something that still meets eye-protection safety standards even if the tint is ilegal.
