The Cosmo is a $ 119, 150 grams device rear brake light shinings bright red to indicate the deceleration of a motorcycle driver. The manufacturer states an extremely accurate advanced accelerometer & gyrometer technology to ensure quick readings.
In addition, thanks to a smartphone integrated application, seconds after your helmet hits the ground, the Cosmo will automatically notify emergency responders as well as your preselected contacts.
Curved to fit any motorcycle helmet, attached to the back and functioning as an attached brake light, it increases any motorcyclist’s safety and visibility on the road. At Cosmo Kickstarter Campaign
I like the idea of a brake light in a spot that is or could be inline with people’s eyes in cars. Especially in stop and go traffic. It could save a life.
