I have been blessed with bad night vision and am shopping around for a good headlight/tail light for my bike. I really want to go the dynamo route for the ability to jump on and go but I am not opposed to battery systems. I need a light with a wide beam pattern, high lumens/lux as possible, and a cutoff to avoid blinding others on the road. So far I am thinking of one of the Busch & Muller models for the bike and a Dinotte for my helmet. If cost was no option what would you suggest? I am not too interested in flashlight systems since they seem to have a narrow beam pattern. I just need to be able to see in the dark for pretty damsels in distress!
