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?

Lasata: lasers are so always the answer.
Keep the beam at low enough intensity (as low or lower than traditional headlamps) and there is no foul here.
High beam and low beam intensity are very close, I think traditional halogen bulbs are 65W and 55W respectively. What is different is where the light is directed. With lasers, you can direct high beam intensity in "safe" directions without as much risk of sending it into oncoming drivers' eyes.
