Sorry to butt in again, but if you picked one of these up, I HIGHLY recommend some headlight film to protect the lens. It appears to be made of polycarbonate, and will scratch easily. All you need is some cheap vinyl film (you can find 12" x 12" sheets on eBay for $5 shipped, just search for headlight film) to keep it nice. I went for clear, but yellow or a light tint may not be a bad idea, because this sucker is BRIGHT.
