Firefly ArcMarker Mk1 ArcMarkers enable an arc-of-fire to be marked clearly and quickly in daylight, dusk and in darkness. Utilising a low-output trigalight® installed in a shrouded slot to maintain security, the ArcMarker also includes a yellow panel to give visibility in day and dusk conditions. Offering great flexibility, applications include trench marking, safe-lane or hazard marking and they can even be used as a model or map-pointer. Firefly Mk1 ArcMarkers are available in black and desert sand enclosure colour options. Illumination is provided by a trigalight® with dimensions of 1.5 x 6.0mm. Standard lamp colour is green, although other colours may be provided upon request. The black, illuminated version of this Mk1 ArcMarker is listed under NSN 6260-99-797-8456. These units are generally supplied in blister-packaged pairs, with lamps included. However, they may be purchased loose and with/without lamps installed.
