In order to advertise F-CELL vehicles that run on the hydrogen fuel, Mercedes-Benz has equipped the car with a video camera on one side, and the other side of the car was covered by a solid coating of LEDs to form a display, which outputs the image from a video camera to the screen in real time.

The invisibility of the car should symbolize that the car does not do any atmospheric emissions and it is harmless supposedly to the environment.
