The Unity Tactical SPARK Green Light is a fully encapsulated, ultra-lightweight personal identification and signaling beacon built for reliable marking in harsh outdoor environments. Wrapped inside a flexible, waterproof silicone shell, this compact emergency strobe easily presses straight onto helmet loop panels, plate carriers, or vehicle surfaces using its integrated hook backing. Users can instinctively push the center of the soft housing to click through four distinct channels featuring constant-low, constant-high, active blinking strobe, and complete power-off cycles. The self-contained marking tool relies on a built-in, non-replaceable lithium power supply that safely delivers over sixty-five hours of continuous runtime while running under flashing profiles. Emitting a high-visibility green light signature, this low-profile safety device can also be paired with an optional magnetic mounting cage to securely weave onto standard heavy-duty tactical nylon webbing.
