It sounds like something out of a sci-fi movie, but laser beam warning triangles and OLED lights that behave like a swarm of bees could soon be standard issue on the latest cars from Audi.

The new Audi car parts are just some of the developments the manufacturer's lighting engineers have been working on in recent months and, if the projects are given the green light, could find their way onto Audi models in the near future.

Perhaps the most striking of these innovations is the OLED (organic light emitting diode) swarm, which sees the rear of the car transformed into a continuous illuminated surface, upon which multiple small red dots of light that move in unison like a swarm of bees or flock of birds can be displayed.

The movement of these dots is dictated by the movement of the car. So, for example, if the vehicle turns to the left, the lights will flow to the left-hand side of the car, while if the driver applies the brakes, the dots will surge rapidly forward.

The quicker the car moves, the quicker the dots will change position, helping drivers in vehicles behind gauge its action.

Meanwhile, Audi engineers are also working on a laser beam warning triangle, which can be used in weather conditions, such as fog or spray, that would make a conventional warning triangle difficult to see.

A laser beam built into the car strikes the water droplets in the air and makes them visible. The car's rear fog light then projects the form of a large warning triangle onto the droplets.

It follows the recent news that Audi has developed a new concept electric vehicle based on its A3 small family car.

Called the A3 e-tron, Audi plans to use tests of the car to inform its future production of electric vehicles for the mass market.
