Also many newer cars have this uber-bright white headlamps, which I think are blinding and actually more dangerous for road safety

  These really need to be outlawed until everyone is using self driving cars.

  The larger problem with newer headlights isn't so much the HID or LED source, but the fact that nearly all cars are coming with projectors. Even halogen looks really bright to oncoming traffic when it's focused down to come out of a small-diameter source. I would be interested to see what we could do with lower power LEDs in an array -- same or more light actually hitting the road, but potentially much less glare to oncoming drivers.

    Legal limits on headlight intensity have been increased several times. In the US, before 1978, it was 37,500 candela. Now, it's 150,000. This isn't just a technology issue; it's not terribly difficult to get 150,000 candela from a halogen incandescent bulb given a decent size reflector or a focusing lens.
