Yeah I know you might think I have lost it here, but now I do mean pump your light. As in charge your lights while pumping.
Now what a great idea have a light that you charge while pumping or just use your pump to charge when your batteries are running a bit low.
20 seconds of pumping suffices for 45 minutes of track-illuminating LED power. Simply pump up your tires, or perform the pumping motions merely to recharge the device, then clamp it into its holder and away you go.
Even though it did win a Eurobike 2009 award it is still just a prototype.
