I have an Edelux headlight, mounted to my front rack.

This is an excellent light. Very bright, with a shaped beam that doesn't waste lumens off in the treetops.



It is powered by a Shimano Alfine generator hub. It is a tiny little thing, really. Not much bigger than a quarter.

The light also feeds power to a rear taillight.

I've had this setup since the first of the year, and it has been flawless.
