I'm sure the LED manufacturers will take full advantage of this opportunity to create "true-light healthy LEDs", for which they can charge double or triple.

#4All the studies I've found seem to say something along the lines of "blue light disturbs sleep", which seems like exactly the needed effect if you're driving at night.

#5Seems like there might also be an opportunity here:

- Install lights that don't disturb sleep so much in neighborhoods.Re: Some cities are taking another look at LED lighting after AMA warning

Because of your eye's sensitivity to different frequencies, the "warmer" colors require more energy for the same effective lighting. Hence, highway departments choose the "daylight" option to save energy.

Yeah, until you drive out of the highly lit area. Then your eyes will have to take some time to adjust to the low light.
