These strobe have been gently used for demo purposes and may have some cosmetic wear and serialization on them, but are otherwise fully functional.
This FMA helmet strobe is the perfect addition to your helmet for signaling needs and has the same functionality as much more premium helmet strobes. It takes one CR123A battery to function. These strobes have a functional RED and IR strobe pattern (IR strobe selected by pressing the 2 side buttons simultaneously)
