Does red light kill night vision?
The Rhodopsin contained within the rods in your eyes are less sensitive to the color red within longer wavelengths of light. Both red and green light at high output will kill your night vision, no matter what color, so keep that in mind. Whatever color you feel helps you more, try to use the least amount possible.
Why do we use red light?
Emergency professionals and first responders also utilize red lights. They help preserve night vision and decrease the overall light signature in low-light situations. The reason for this is that red light does not cause the human eye pupil to shrink to the same degree as more bluish/white light.

What is the universal distress signal?
