CDNN sent me something like this
http://www.amazon.com/Carson-Optical-LED-Flashlight-Red/dp/B000WG0LPQ
as a gift along with some stuff I ordered from them years back and I use it all the time at night mostly to look for something in the truck or in my pack without giving our position away. Mine is a little different then the one on Amazon and says, “Browning” on it. It’s cheap and may be a little small to navigate with so something like these are probably more of what you’re looking for.

Be advised, people can see your red light from a distance but not nearly as easy as white light.
