I may have a set for sale shortly - when I get round to fitting the replacement clear ones I acquired. Both lights have never been removed and are in excellent working order, having only done 31,000 miles.
Mine are have gone cloudy because of scratches. I read about to restore treatments but I am not sure if they last because you are effectively polishing the lense and taking about the uv protection. Not that it has any now that it's cloudy and scratched up...
