From a single lamp to dozens of LEDs - and now the future's headlights comes with HD technology. Up to two million micro mirrors provide brand new possibilities for the car's headlights to not only shine exactly where needed with exact precision - but even projecting messages on the road to other road users.

The new generation of headlights controlled by a control unit, which Mercedes-Benz developed, will use HD pixel-technology to help cars find their way in the dark. The new algorithms are controlled by detailed information about the surroundings collected from the sensors in the car. Then, in real time, they calculate how strong each of the two million pixels will shine.

Different sensors, such as radars and cameras, recognizes other drivers on the road and other conditions, they also evaluate incoming data over the course of a few milliseconds. It determines how the headlights will spread the light in the best possible way in any given situation. So the driver gets the best possible vision without dazzling other drivers in the eyes.

Digital Light is not just about having the perfect light frame in all situations. It also gives the driver assistance and support in difficult situations, such as when driving through narrow roads at dark roads.
But the new technology also makes it possible to project messages on the roadway. Headlights can draw marking lines on the roadside if they are missing on more "non-developed" roads. Or display messages like arrows or warnings live on the roadway. The system can also communicate with other vehicles and provide them with information about what the sensors have discovered before the other vehicles are in that same place, thus making the tech more efficient with patches and time.

For example, the car can project a crossing point, thus it can show a pedestrian that they are discovered by the car and that it is free to pass. Digital Light is an important step towards accident-free traffic and self-driving cars. When the first vision was shown on the concept car F 015-fair two years ago, this felt like science fiction to many. But it has already been tested on demo vehicles, and it will probably not take to long before the first cars with the new technology are being used by consumers.
