You have a Mystique (like me), might be worth a call and see if there is a deal for Mystique lights. They are still not cheap. On e-bay there are aftermarket ones, but they may not fit right. I wetsanded and polished mine in stages, they need a rebuff and wax monthly. Lots of work, many have done it. There still will be a haze in the top, but not yellow.
