Audi has revealed a car lighting technology ‘swarm’ made up of organic light-emitting diodes that respond to movements of the car. Audi’s swarm tail light technology with thousands of small red lights that cover the width of the boot, able to move both left and right, show other drivers what the driver it doing according the where the wheels are aiming. This new Audi Matrix OLED lighting and the tail light concept Swarm are pretty impressive. A kind of tail lights we’ve never seen before.
