If you've cycled all day long on a bikepacking trip or cycling tour, you know running lights all day long is extremely difficult in that batteries on most lights simply won't last.  It's proven that lights on bicycles decreases the risk of being struck by vehicles and certainly is required after dark hours so what's the solution?  A son hub dynamo and a sinewave cycles light. This solution Jerry went for on his Salsa Fargo has helped eliminate the problem of lights for long rides and also gives a possible solution to trickle charge a battery pack along the way as well!  Thanks for bringing the Fargo down, Jerry and giving us all a chance to see the new setup :)
