8 Led Headlamp with 5 White and 3 Red. Great for Hands-free Operation. Nifty Combo Headlamp Nifty because it&#39;s got (8) LEDs and (3) modes: (5) white LEDs all-on for use as a, well, headlamp, (3) red LEDs flashing so the cave-rescue team can find you, and (3) red LEDs steady-on for that behind-enemy-lines work. The whole thing is attached to an adjustable, 3-strap elastic headband which also holds the battery compartment at the back with its own red LED bar as a taillight. Weather resistant. Runs approx (12) hours on the (3) alkaline "AA" batteries that you add.
