Unity Tactical SPARK Helmet Mounted Marker Light Green

The UNITY Tactical SPARK Marker Light Green is a small personal identification and marking light designed for visual identification on gear. Originally developed for industrial safety use, it attaches to helmets, plate carriers, chest rigs, and other kit that needs illuminated marking.

The light has a black matte polymer finish and a flexible silicone body that encapsulates the LED, which the retailer describes as water and damage resistant. A center press cycles between constant-on, blink, and off modes, with a positive click for tactile feedback. The included Velcro backing provides mounting. The retailer lists a runtime of more than 200 hours and describes the unit as disposable.
