I just want to not worry about lighting. Harris lists a ready-built wheel for $175, and I would be willing to spend that (and more) to insure that I am always well lit this winter. I have several questions.

first, can these be used to power the lights I already have? I don't know squat about electricity. I have a 2xAA fenix that uses 3v. I have a 4xAA 5w DiNotte that uses 6v. From what I read, the Shimano hub output is 6v. Is it realistic to power the DiNotte with a generator hub?
It would work, but likely be rather dim at lower speeds. Worth a try if you're handy with a soldering iron and shrink tube. By the way, "Dynohub" is a Sturmey-Archer trademark. ;-) I prefer to call them "generator hubs."

I also like that it doesn't mount on the bars. I prefer not to have the everyday light mounted on the bars.
A lower mounting position casts potholes* and other road hazards into sharper relief, because of the shadows they cast.

It wasn't on their special order page but I thought it might be too new.
I'm sure we can order these. Not familiar with that new model yet...

I really do not recommend wired tail lights. Modern self-contained "blinkies" are so reliable, and so parsimonious of batteries that I consider them a much more reliable alternative to anything that involves running wires along the bike from front to rear.
