A brake light is standard equipment on cars, but this safety feature is largely missing on bicycles. Now two Harvard students are stepping into the breach with a helmet called Lumos, which is equipped with an accelerometer. As soon as it detects a braking maneuver, a clearly visible LED triangle light on the back of the helmet lights up red.

But the innovative helmet doesn't stop there: a left/right blinker can be set on the Lumos helmet via a remote control on the handlebars. And at the front of the helmet, white LED position lights once again ensure that the cyclist is clearly visible.

In order to supply the accelerometer and LED lights with power, the helmet houses a rechargeable battery that can be powered via USB. One battery charge should last a week if the helmet is used for 30 minutes a day. The weight of the end product is around 410 grams, which is roughly the same weight as a helmet with a skateboard-style hard shell.

The start-up funding via Kickstarter is already in the bag, and the first helmets should reach the first customers from April 2016.
