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."

      I think light in general keeps me awake... I drive a car with an in dash DVD player, GPS, sattelite radio (glows blue) and a bluetooth thing (glows blue too) maybe thats why I feel awake when I drive? I have no idea.

    I find a flashing blue light in the rear view mirror certainly wakes me up.

    Seriously though, it would be better to just not drive when tired. Also wouldn't screwing around with your internal body clock mess you up more?

    Blue lights are more likely to wake you up not because you think it's morning, but because you think the police are chasing you. One time I was driving, and for some reason was paranoid that there was a cop around the corner and I came across a house covered with blue Christmas lights. That woke me up.

    Same here, red lights dont keep me awake, neither do blue lights on their own. However I've always found that turning on a flashing red and blue light behind me will instantly make me awake and fully alert,no matter what. The effect is amazing :)

    When I die, I want to go peacefully, in my sleep, like my grandfather.

    I think this is a bad idea. I mean, when I travel, I sometimes go by bus. Never get any sleep on a bus.

    When I travel by plane, I never get any sleep. Kids yelling, flight attendants interrupting me.

    But, when I'm driving myself, I can fall asleep no problem. Get some of my best shuteye when I'm behind the wheel.......

    Ahhh yes, I cherish particular hatred for those blue lights. Once, in my youthful folly, I got the Netgear router with the light dome that was reminiscent of a flying saucer. I was in college at that time, and ever night I regretted it as my router just happened to come up about to my bed height. Every night felt like I was about to either be abducted by aliens, or sleeping with a poltergeist (yes, it came with a black cap to cover the lights...no it did not really work).

    Yes, I agree totally here! Furthermore, there's a worrying increase (on UK roads at least) headlamps with a *nasty* blue tint to them. I've no idea what they're called but they *really* screw with my eyes, mostly on BMWs and boy racers. Night vision gets all messed up and there's noticeable scarring (after image) - anyone know what the bulbs are?
