Usage of Red flashlight and Green flashlight: Human's eyes are most sensitive to the red or green range of light, but the red light or the green light is less sensitive for the animals in the dark, like hogs, coyotes, fox...so you can find them without disturbing them. They are good for night hunting observation.
