I rather go with batteries for the taillight rather than run wiring from the front dynamo hub.
I currently have (or did till the front popped off somewhere along the road) a Planet Bike Super Flash. Not the greatest solution for a rack though since it's tall. I need one of the horizontal lights that are really meant for mounting on a rear rack.
Thanks!
