Been through 3 or 4 different Mic Lights and finally got the one Helofan is talking about... best one yet for sure, but still a mic light! Unless you can put what you want to look at right on your face, it doesn't do much for lighting things up, IE a kneeboard or instrument panel/switch, especially if you're staring into NVGs (which is like staring at two flashlights). Finger lights work well, but I ended up settling on a light around my neck. Just pick it up and point it where you want it, no hassles. I use the Phantom Hawk:

...and like it a lot. I also ran with that one attached to my kneeboard for a while, also worked well with a finger light. Seen a lot of the big ones running around here too. Some guys at work have gotten a little rubberized square light that runs off a 9V battery, don't know who makes it but it has a push button for medium, high, and flash... but always stays on in the low intensity mode, perfect for identifying switches and reading maps. Very cool light, wish I knew who made em!
