I just got turned on to these awesome LED lights which are ostensibly for cycling but can easily be used for running and hiking and such. Super bright, with wide field of lighting, powered by any external usb battery pack etc.

I plan to order a couple sets and just wanted to see if anyone interested in going in on a bulk order. Just trying to guage interest at this point.
