Re: head lamps?
As you know Casey I am from the greatland and most of the time I am fly fishing it is light late out if it gets dark at all. That being said I always have one in my vest. I think any of the modern LED work fine, the one I have which is also a Petzl has a red lamp and strobe. While I havent needed them for survival purposes, I can see where having a strobe will come in handy. I have used my plenty of times hiking in and out of locations, and tying knots etc in low light. For me it is a dont leave home without item in my vest.
