I looked up purchasing from Polaris dealer but was shocked to find the price was $249!! The sticker was still on the light tube and showed part number (Hella) 1AL00999802. Looking this up you can purchase from other uses for about $150. I only needed the front glass so in looking up 90mm Hella lights I found one on ebay for $19:
The lens is a thick glass but is glued into a hard plastic housing. Was fairly easy to carefully cut up the plastic housing with a dremel and remove the glass. As the installed one was already cracked, a hammer and screw driver got that glass out with no problems. Cleaned out the old glue and put a bead of silicone glue into the housing and set the glass.
