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. [SCDC via Gajitz]
