So we sourced a company in Japan that sells replacement sideview mirror lenses. The replacements are blue tinted to reduce nighttime glare and have a slightly convex shape to convey a more wide-angle rear view. These are OEM replacements designed to replace the OEM sideview mirror lens.
For 2010 owners, it seems that these are also compatible with the OEM heating elements with small modifications.
As the minimum order is 10 sets, we are trying to see if there's an interest in bringing these over to market. Price range would be around $250/pair shipped.
