Sprak is a tiny personal identification/marking light with a big personality. Originally designed for the safety of workers on oil platforms, Spark is a practically unnoticeable addition to helmets, plate carriers, or chest rigs. Spark is easily activated by pressing its center. It is cycled on/off by pressing it again. A positive click can be felt when the light is not placed in a spot visible to the user. Spark is fully encapsulated, making it water resistant in a flexible silicon body. The LED will blink red when activated. Spark is backed with Velcro for ready placement on tactical and industrial gear.
