Red Lights are good for night vision
I just thought I would throw in a little something here. Red lights are better for night vision than amber, green, blue, or white. I don't have any real science to back this up, although I'm sure I could find some. Just an example that always seems to work.
Have you ever noticed how much an LED lit clock will light up a pitch black room, unless it uses red LED's? If you don't believe me, just look for yourself. The more the color of the light moves from red to blue, the more you can actually see the light from the clock in the room. It seems that our eyes are less sensitive to reds, at least while in the dark.
When I had the dash torn apart on my LT, the first thing I did was to darken the cruise control lens with a black marker. That amber light glowing in the corner of my eye was a nuisance. I could actually see the glow coming off the backside of the windscreen. Now that the light has to shine through the marker and lens, it is much more subdued.
I just might do this red LED thing this spring. Looks like a good idea.
