Thank you first of all to those people that replayed to my first post, there were some good suggestions and I really appreciated them. I was wondering how many of you transfer your light between several different bikes or if you have a light for each bike. I was contemplating a hybrid system that would use a generator and batteries. The problem with this system is that it would not be easily transferable between bikes, so I was just wondering how many people out there use multiple lights. The problem with the generators is that they only produce between 3 and 6 volts and the problem with battery powered systems is the chance of running out of juice when you are ridding.
