Blue Lights To Reset Internal Clocks
holy_calamity writes "Researchers at RPI are testing the effects of putting blue LEDs inside cars to keep drivers alert. People driving through the night are much more likely to cause accidents because our circadian rhythms just want to sleep — blue light at around 450nm wavelength can fool them into thinking it's morning and keep them awake."
Blue wavelengths also have the nasty side effect of destroying night vision almost instantly, fooling the pupils to contract - likely for the very same reason it fools the rest of the body into thinking its daylight too.
Not a desirable or safe side effect when making something specifically intended to be used for driving in the dark. It's why the military uses red lights in their vehicle cabins and cockpits.
More careful drivers won't drive at all when drunk. Just *my* own experience. As for statistics:
"For all Americans between 5 and 35 years of age, motor vehicle accidents are the number one cause of death. Over 50% of these accidents are caused by alcohol impaired drivers."
