Emersongear - Velcro Distress Light Marker - Blue is a small LED powered Light designed for use as a marking device to donate Locations and Team Colours for Identification. The Body of the Light is constructed from Polymer, with a Gel encased LED Light, making it waterproof. The Marker comes in a plastic case, which features Male Backed Velcro Body, meaning that it can be attached to Helmets, Rigs, Bags and Vests, and a loop which allows the attachment of Lanyard Loops and Strings. These lights are also great for marking areas for your team mates, or placing on backpacks so they can be quickly found in dark or unlit areas. The light features three modes, on, off and strobe for easy identification. This is a perfect purchase for those who are always losing items in the dark, or for Milsim players who want to allow their team to quickly identify them during night missions.
