The prototype helmet, created by Swedish auto giant Volvo also warns a vehicle when it gets too close to a cyclist.
The helmet lets cyclists know if they are in a vehicle's blind spot so they can take action to avoid a collision.
It works with smartphone fitness monitoring apps that track the location and speed of a cyclist, BBC News reported.
The information is shared with any vehicles nearby that are equipped with the firm's City Safety system. This alerts drivers to the presence of a cyclist even if the rider is in a blind spot or when visibility is poor.
Drivers are alerted through the car's head-up display and the rider is warned via a light mounted on the helmet.
