Was messing around Kickstarter and came up on the Lumos helmet. It looks like they've met their kickstarter goal, and the project is due to ship in 2016. There is still about 20 days left on the project to sign up as an adopter/supporter and get yours for $99. I'm tempted to give it a go. This is a helmet with built in brake lights and turn signal. The break lights are accelerometer based, with the outside turns and the triangle in the middle lighting solid when it notices you slowing down. There area also white lights mounted on the front that flash for more visibility for oncoming vehicles. The turn signals are controlled by a wireless remote that you mount on your handlebars.
