Braking-sensitive rear light - Kickstarter project
Ever dreamed of your rear light flashes when braking?
There's a Kickstarter project trying just that.
Using motion sensor (like Wii) means no wiring is required. Just click on like any other rear light and (they claim) it does work like a tale lamp on motor vehicles.
If you're interested please support their project on Kickstarter website:
