I have a set of Cee Bailey's head light protectors on my 2013 FJR. Last weekend something hit the right side and shattered the protector into three pieces; the light lens is undamaged. (I know, not a BMW, but it happened on the way to a BMW event ) I sent Cee Bailey a picture and asked if I could buy just the one side. I had a response in a few hours saying that if I would provide a mailing address they will send me a new set at no charge, including shipping. You cannot ask for more.
Do not know why the pics upside down, but a crack is a crack no matter the prospective.
