I wear a belt pouch, Nit-ize I think is the brand, that I carry a mini-mag, Gerber multi-tool, mechanical pencil, black sharpie and a silver sharpie. This belt pack is low profile and saves me hours a week, I need a quick tool and it is on my belt.

I like the mini-mag that has a single LED ant takes two AAs. Twist on and I am good to go, lasts forever.

There is a new type of light out there, it is about 4" long 2" wide and has one side coverd in LEDs and on the other side is a magnet. This is great for rack work, sticks to the side or inside top of the rack, small enough to fit in your tool bag but is really bright. It also has a small hook on it so you can hang it from a wire or nail. I have no idea who makes it but I have seen it in an Ace Hardware store and in some convince stores.
