Whether you're biking in the dark or in a busy area, there's always a risk of not being seen. Cosmo Connected wants to fix that with a smart brake light that attaches to the back of your bike helmet. Eight LEDs stay lit for visibility, with an accelerometer that detects when you come to a stop and automatically lights a brake light. The same sensors can also detect if you've had a fall and notify friends or family — or, with an optional subscription, emergency services. Cosmo can also serve as a turn signal, lighting up LEDs on one side of the helmet or the other to indicate direction. You can program in a route beforehand and then Cosmo will automatically activate the lights when you reach each turn. You can also trigger turn signals manually via the smartphone app or through an optional remote that mounts on your handlebar.
