The tail light concept is aptly called "The Swarm" and consists of an array of OLEDs that change according to the car's movements. Making left and right turns see the OLEDs flow in the corresponding directions. Braking will display the lights flowing forwards and accelerating will force the OLEDs to speed up.
Audi says the concept tail lights are meant to provide more information to other drivers on the road, but are they more distracting than helpful? Check out the gallery and some new video below and see what you think.
