I just finished mounting a Supernova E3 Asymmetrical headlight and a Supernova taillight on my Big Dummy. I had to make a sheet aluminum taillight mount to bolt to the rear deck but the headlight and taillight wiring were long enough without having to add any wire. Considering the length of a Big Dummy I was surprised. The taillight mounting plate is large enough so I also have a Radbot 1000 mounted below the Supernova taillight.

My front wheel is a 36 hole Shimano Alfine 501 dynamo hub laced to a Salsa Gordo rim. This is the same make of rim as the original wheel which I am keeping as a spare.
