The color red helps to preserve a persons 'night vision'. If white light were used and a soldier heard something and tried to look out into the darkness, he couldn't see much.
true but not totally true. red still makes most colors visible to the eye more-so than other colors and it has the least amount of ambient light so the soldier cant be detected while reading a map by the light reflecting off of it. red also doesnt travel as far of a distance than other colors so the enemy cant see it far away or even fairly close up. finally red is just the best color to use at night because you can still see ahead of you (not far) but someone else wouldn't see the light unless they accually saw the bulb itself, the ambient light (excess light emitted which is unused and not in the focused beam) cant be seen at all at night over a certain distance too.
hoped that helps
