What light source is in your B.O.B.?

[Mtbkski]

I currently have a flashlight. But realize that there are times that you may want light for long periods of time. It is then, that light sticks would be handy. But you can't always count on them. They can be activated without you realizing it, and then you don't have a light.

I also keep two small candles in my bag. Light source. Build a fire with.

Well, check this thing out. It isn't cheap. But is is the multi-tool of the light world.

What light sources are you guys carrying. Flashlights are expected. What other sources do you have if any.
