re: Red dash gone



This doesn't make sense.  My 200+ watts of white light illuminating the 
road in front of me don't affect my night vision?  By the same thought 
process as long as I don't look _at_ the sun, just the lit results, then 
even daylight wouldn't affect night vision.  Yes, I am aware of being 
blinded by other drivers, but that affect would be similar to staring at 
the sun (don't please) briefly and then having diminished vision for a 
period in normal light.  This is due to the adjustment of the pupil, not 
the eye chemical that gives night vision.  I know that red light 
preserves night vision, I just question whether red dash lighting in a 
vehicle relying on bright white lights for forward vision serves that 
purpose.  BTW, I like my red dash lights.

Michael is right, unless the entire US Army is wrong. It is a proven 
fact
that red light is the least disruptive to night vision. All US military
vehicles use red gage lighting, to preserve night vision. Your 
headlights
are pointing away from you, so they don't affect "your" night vision. 
You
look "at" your gages, so white light glaring back at you "would" affect
your night vision. As Michael stated, other vehicle's headlights tend to
leave you slightly blind, especially if you look right at them.--
