A headlamp is part of the basic equipment for hunters, whether to find the Ansitz or for tracking. Compared to classic flashlights, headlamps have the advantage that the wearer's hands remain free.
Good headlamps have multi-level white light settings as well as red and green light.
Game is said to be less sensitive to red and green light than to bright white light. Green light allows the human eye to perceive contrasts more sharply, while red light has the advantage of having the least impact on human night vision. However, colored light has no advantage over white light when shot.
