UFOs on the M4: Audi reveals bizarre 'swarm' light that turns the back of its cars into a pulsating screen

• Lights designed to look like moving swarms of animals
• Respond to movement and direction of the car
• As the car speeds up the 'animals' move faster
• Technology uses lights made from organic material
• The AA warns it is 'best saved for art galleries and aquariums'

Audi has revealed a car lighting technology that can make the back of its cars show bright patterns to other drivers.
This 'swarm' is made up of thousands of small red lights that cover the width of the boot and react to movements of the car.
The screens are designed to show other drivers what the driver it doing - but motoring organisations told MailOnline the technology should stay a concept.

Audi's swarm tail light technology is made up of organic light-emitting diodes that respond to movements of the car

When the wheel is turned left or right, the lights flow in the same direction. When the driver presses the accelerator the lights move faster, and when the car brakes the lights flow forward

When the driver turns the wheel, the red dots flow in the direction it has been turned.
When the car speeds up the number of dots, or 'fish', increase and they flow faster around the surface.
