Pedalite

With the short winter days, you're more likely to be caught out after dark on your bike. And if you're not wearing some reflective gear, you're at risk of becoming asphalt seasoning. The Pedalite ($90) is an illuminated bike pedal that makes you visible. The best part is that the Pedalite pedals use no batteries — each has a tiny gear generator and energy storage capacitor that charges while you pedal. They'll even continue to flash for up to 12 minutes after you stop pedaling.
