Bloomberg:

Most people don’t turn on their car’s headlights and think, I wish they were brighter. Shuji Nakamura is not most people.

The Nobel Prize-winning illumination scientist has spent the past five years developing a laser-based lighting system. His company, SLD Laser, says the new design is 10 times brighter than today’s LED lights, capable of illuminating objects a kilometer away while using less power than any current technology. And unlike a regular, dumb headlight, the laser can potentially be integrated into current and forthcoming driver-assistance systems.

Do headlights need to be brighter?

    Headlights need to be SMARTER.

    What if the headlight were more like a projector. Certain pixels of the light output could then be selectively dimmed in the shape of an oncoming car.

    Other shapes could selectively be de-illuminated as well, such as speed limit signs.

    Instead of making headlamps out of lasers, make lasers out of headlamps.

      You wouldn't blind other cars. But I thought you might say: you wouldn't be able to see pedestrians on the road.
