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.
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. When the driver brakes, the dots slow down and flow forward onto the top of the boot.
Audi’s swarm lights are made up of thousands of organic light-emitting diodes (OLEDs). These diodes can be added to any surface. When an electrical charge is put through this organic material, the diodes light up. Audi claims these lights mean drivers in cars behind can always see what the driver of the car in front is doing. However, a spokesman from the AA had a different view, ‘The Swarm is a delightful concept design but under current lighting regulations it is probably best saved for aquariums or art galleries.’ If they pass safety tests, the swarm lighting could replace the traditional braking lights on future Audi cars. Audi unveiled its swarm lighting technology at the Consumer Electronics Show in Vegas last week.
The German car maker also announced a laser tail light.
In good visibility, the laser tail light shines a fan-shaped red line from the back of the car. It is used to prompt the driver behind to keep a safe distance, similar to a stop line. In fog or spray, the laser beam bounces off the water in the air and turns the line into a triangle, similar to the warning triangle used on breakdowns.
