The sole purpose of a red light is to preserve night vision. Have you ever noticed when you shine a bright white light then turn it off in the dark, you can't see anything? They also reduce the itensity of light output. Meaning if you're using one, it's not going to light up an entire area or be as noticable for someone else to see or detect. No better friend, no worse enemy.

I have no idea what the science is behind that claim, but it seemed to work well enough for us. Blue also seems to cut through fog and haze the best, but again, that's totally non-scientific anecdotal evidence talking. - CyberShoe res_novae  Location: NoVA Gender: Male  |  |  Blue-Green or Red filters? <Reply # 22 on 2/8/2006 5:01 PM >   I found an old Army Training Manual (circa Desert Storm) my dad brought home from work. Now, common knowledge states that if you don't want to be seen, use a red filter on your light. This manual clearly states at night, use the blue-green filter instead of the read. It gives no reason or purpose why. I know a big reason red is used is in hunting/animal calls, where animals cannot see the red light. However, people can, and to me it seems blue-green works well because it blends with the dark of night. Does anyone have anymore information on which light filter to use? Edit:: Haha, should've searched...thanks for merging.
