Riding bicycles at night is dangerous. It's hard to see the road and it's even harder for people to see you. Sure, you can get light attachments for your helmet—but they all look goofy and cluttered. That's where the Blink Bike Helmet rides in.
The Tron-looking helmet has LED turn signals, that you activate by touching, on the left and right of the helmet and LEDs on the front and back. The helmet is only a concept right now, but someone should get on making one ASAP. I, for one, can't wait for them to distract drivers with their coolness at night.
