Description
The Unity Tactical SPARK is a personal identification and marking light built for anyone who needs a low-profile way to stay visible to teammates — on a helmet, plate carrier, chest rig, K9 harness, or vehicle. It was originally developed for industrial safety use, which tells you something about its design philosophy: straightforward, durable, and meant to work without fuss when conditions are rough.
The body is fully encapsulated in flexible silicone, which makes it both water resistant and able to absorb the kind of incidental impacts that come with field use. A Velcro backer handles attachment, so placement can be adjusted quickly across different pieces of kit without any tools or mounting hardware. The blue LED cycles through constant high, constant low, blink, and off with each press of the center button, and the button produces a distinct tactile click so you can confirm activation without looking at it — useful when gloves are in the way or light discipline matters.
With a runtime rated above 200 hours, the SPARK is genuinely disposable — you can issue it, use it through an op or exercise, and replace it without worrying about battery logistics. That runtime also means it functions well as a persistent marker left on a static piece of kit rather than something you have to manage actively. At this price point, keeping several on hand as spares is a practical option for units or teams that need consistent, reliable IFF capability across multiple personnel.
