Fancy little gadget for those inclined - MoD issue, NVG compatible, aircrew finger light - gives a pale blue light, good as a task light for navigation/map reading, close tasks, etc. Ex-wife got it for me from Man at Q&M when she was attached to JSFAW. I’ve used it once at work but don’t really need it. Off/low/high controlled by ambidextrous buttons. Adjustable Velcro strap. Storage pouch. Price includes postage and PayPal G&S fees.
