Our famous battle-tested, Soldier-proven Phantom Warrior TLS tactical flashlights are already in the hands of your unit. But you need BOTH a tactical flashlight AND a rescue beacon in your kit. Our engineers have come to your rescue with an advanced optical design creating a supplemental lens that turns any Phantom Warrior TLS into the perfect rescue beacon. Save precious budget dollars by using one proven light for BOTH purposes! Saves pocket space, too! The Phantom ResQ stores on the lanyard of your flashlight, or any 550 paracord. The lanyard remains adjustable as before, but when the need arises (and we hope it never does,) just slide the ResQ lens onto the top of the light and the most covert of lights becomes the perfect safety beacon utilizing any of the built-in flash modes or colors of your light. We've tested it against the standard issue personal military strobes and...WOW! Our new ResQ lens system is BRIGHTER, won't break or burn out, and runs on 4 AA batteries. When you need to be covert again, simply remove the lens.
