World's most visible bicycle taillight. Why VizMo: We believe visibility is key to bicycle safety in traffic.  VizMo is the first bicycle taillight to rise above the bike. Its height plus significantly larger illuminated surface area provide an advantage over existing taillights by making bicycles more obvious to motorists, both up-close in traffic and from a greater distance down the road.   VizMo’s conspicuous differentiators and greater visibility will lead to a reduction in traffic accidents involving cyclists.
