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?

Depends how they're aimed. The current issue we have with those bright head lights is that they're often not aimed properly. If they're aimed properly, you don't get much extra distance out of the lights, but you do get a bit of extra light bouncing to the sides.
One of the big concerns I'd have is that since they are more focused, that you'd lose out on the light that you'd have lighting up the sides of the road where pedestrians and animals that might come into the roadway are before doing so.
In general, this seems like a solution in search of a problem. At night when you're using the headlights, you should be going more slowly anyways, because you'll see far less of what's going on than you would during the day.
