So, the upward glare and the need for a glare shield is a feature? I can just see their ad copy: "The new Ixon Dazzler® is specially designed to teach bicyclist to remain seated at all times. When climbing out the saddle, the Dazzler® uses specially designed optics to focus a beam of light into the eyes of the cyclist which encourages them to remain in the saddle. The optics have been designed so that only the cyclist experiences the Dazzler® effect and the motorists around the cyclists is protected from any unwanted or unneeded light.

The Dazzler® joins the other fine products in the Ixon line of training devices including the Popeil 'Bed Of Nails'® saddle...based on patented Vlad the Impailer technology...which makes saddle sores a thing of the past. Remember, if you can't sit down, you can't get saddle sores. And the very popular Ronco Bladed Tape® which uses embedded razor blades to encourage a light grip on the handlebars. And who can forget the Cinelli Death Pedal®? 'If you can't take your feet off the pedals, you won't stop pedaling.'"
