Red light is most often used to enhance, or more properly, not harm night
vision. Red light provides great contrast and is not visible to the human eye
over long distances. It also works well with night vision scopes and goggles.
Photographers use red colored light when doing night-time photography because it
provides contrast while preserving the natural shadows developed by darkness.
Red light cuts through smoke better than white light and, with the exception of
red lines and marks on maps and charts, it makes reading in low, or no, light
possible. Police and military units like the red LED for night operations
because it will not interfere with night vision technology and canít easily be
picked up by other people.
