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?

Yes, the US stays behind in automotive technology because the DOT spells out exactly what is permitted, meaning anything else is NOT permitted. Seven to ten years after Europe and Asia adopts something new, the DOT gets around to approving it. In the traditional sense of conservative, our DOT is ultra conservative.

As well it should be, at this point the essential bits of how to build and operate a car safely is pretty well established. Additional features and the like should be added and changed cautiously.
The bigger issue tends to be that we allow cars to use the brake lights as brakelights and turn signals which causes all sorts of mayhem when the car behind you has to guess from first blink whether the car ahead is braking or about to turn. It's foolish and just there to save a few dollars.
