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?

For me, you miss the "funny" mark. But, you do hit on something. Maybe all those high intensity light sources should be mandated to be self dimming. Even professional truck drivers neglect to dim their headlights these days, or are slow to react when they meet a vehicle. Headlights that dimmed themselves immediately when meeting another vehicle at night would be great. Or, measure the lumens coming in, and dim when the light level reaches that of a rather dim, but legal headlight 3/4 mile away. I chose 3/4 mile distance, because that is how far away the HID is blinding. With old, incandescent headlights, the law said lights should be dimmed at a distance of 500 feet, but we can't use that as a safe distance with today's lights. (actually 500 ft was inadequate even with those headlights of days gone by)
