Cosmo's bike light works with a companion app on your phone. Here, you can trigger a flashing "emergency alert" or make left and right signals by mashing the screen or pressing the company's optional, handlebar-mounted remote control. It will also be possible to enter your journey beforehand and trigger turn signals automatically via GPS tracking. Finally, Cosmo Connected says the accelerometer will double as a fall detector, notifying friends and family in the event of an accident. All of these features are free, though an optional service (it's not clear if you'll have to pay for this, however) can be set up to notify emergency responders too.

The Cosmo Bike light will launch in September for $60. It follows the Cosmo Moto, a connected brake light for motorcyclists that was funded on Kickstarter last November. The helmet accessory has a similar feature set and is available in glossy black, glossy white and matte black for $119.
