If anyone is looking for mirrors for their Vision, then check this webpage out. The mirrors are actually snowmobile units but are similar to the Vision's. Quality is good and the prices are pretty reasonable (in Canadian dollars).

Then go to page 294 and 295.
If you visit my Vision Blog (http://motorplow.blogspot.com/), I just added an entry about the mirrors I have on my fairing. I also added a link to the "The Rider's of Vision" website. I like the mirrors I have on my bike. They work well and actually allow me to see behind my shoulders.
Enjoy,
