That's a terrific idea! I'll implement that one immediately! Thanks!
The newer ones have a micro processor that allows many differing modes of light. We have used the IR versions in different blink mode speeds to ID each other in buildings during exercises. Think out the threat at hand before ya do that of course.
Also when you add or remove the Photon III twist or spin the light off the bill of the hat as a direct "pull" will open the battery back.
Mine rides on a piece of 550 cord that I use as a neck lanyard. The 550 cord is knoted with a figure 8 knot on each end and I then connect them togeather with 2 O-rings from a standard scuba tank. That way I don't lose my head when exiting transport or hit a wait a minute vine. Very durable for a Photon and can remain on the lanyard to attach to the spot on the underside of a boonie hat.
Just think it thru and you'll see the possibilities and different colors that are available.
Also can be used like a IR chemlight and spun at the end of the neck lanyard to make a big circle to signal NOD/NVG equipped vehicles or troops.......again with care for the situation encountered of course .....but you know that by now eh !
Stay Safe !
