How do the laser headlights work in the BMW iVision?

I've heard that the BMW iVision has unique laser headlights. Can you explain how they work and what makes them different from traditional headlights?

The laser headlights in the BMW iVision use laser diodes to produce a highly focused and intense beam of light. This allows for a longer and brighter range of visibility compared to traditional headlights.

The lasers in the BMW iVision's headlights are also more energy efficient, resulting in less drain on the car's battery. This is because they require less power to produce the same amount of light as traditional headlights.

One thing to keep in mind with laser headlights is that they still require some form of conventional headlights to meet legal regulations. In the BMW iVision, the laser headlights are paired with LED lights to ensure compliance.
