After spending the afternoon searching online some more, will try an add on battery run sidelight and see how that goes.
As for a second dynamo light- does anyone own a Luxos B??? I don't know if I should just get a Luxos B, another Edelux II, B&M IQ or other?... I kind of want to try something different but also want it to be super reliable quality build like the Edelux is.
