Firefly Kit Markers enable users to identify assets or locations in the dark without resorting to electric torch or 'cyalume' chemical lights. Visible from distances of up to 35mtr in darkness with the naked eye, nine visible colour options are available so that identities and functions can be differentiated by colour. Super Kit Markers utilise a corrosion-resistant wire screw-clip to provide flexible, quick and easy fixing to portable and fixed equipment. Each Kit Marker incorporates a 3x2.5mm trigalight® housed within a tough, clear polycarbonate enclosure. Simple, reliable and very effective, operational efficiency and safety are enhanced in darkness.
