Firefly Bivvy Zip Markers are self-powered self-illuminating allowing tent, Bergen zips, bivvy bags and sleeping bag zips to be marked so they can be seen, located and operated by personnel in darkness without using electric torches or cyalumes. Visible from distances of up to 10m in darkness with the naked eye. Bivvy Zip Markers utilise a compact, stainless-steel split-ring to provide quick and easy fixing to your equipment. Each Bivvy Zip Marker incorporates a 1.5 x 6mm trigalight® housed within a tough, clear polycarbonate case. They are also suitable for covert, general marking applications as the Bivvy Zip Marker's limited light output offers a restricted viewing distance. Simple, reliable and very effective requiring no batteries or charging these enhance operational efficiency and safety in darkness. There are no switches to guard and no parts to break or fail.
