No, the Vololights only work with a 12v system but the conversion is really simple. Faizal, at Vololights is a rider and is really cool. He helped me out and donated personally to the charity. You can also donate here www.ride4courage.org NOTE: I TAKE NOTHING FROM DONATIONS... The dirtracks.com things I got were the engine guard, pannier racks that can "host" soft bags AND rotopax and the bigger tail rack. Fred was great to deal with and likes the charity.
