The XS Scuba LED Glowstick in blue is a compact light for underwater signaling, diver identification, and marking equipment in low-light conditions. Its glowstick-style design makes it easy to attach to dive gear, helping teammates identify a diver or locate equipment during night dives and other limited-visibility activities.

Use it as a marker light on a BCD, tank, stage bottle, or gear bag. The blue light also makes it a practical addition to recreational, technical, and public safety dive kits.
