The Million Mile Light
Yes, the Million Mile Light will go for a million miles, but only if you can. The tiny, battery-free clip-on device is powered by motion, and intended as a safety light for runners, walkers, and breakdancers engaging in spontaneous midnight throwdowns.
The Million Mile Light generates a pulse of 30-lumen light with each stride, regardless of how fast, slow, or clunky you move. Each pulse has a 200-meter visibility. The pair of LEDs sit inside a 2-1/2" tall casing that has an IPX4 rating for use in rainy, splashy, and sweaty conditions. The light has a total weight of just 1-1/2 ounces.
The Million Mile Light comes from the same people who created the FlipBelt fitness storage for runners and athletes.
