I've got a Surefire 6P on my belt right now - it's been there or with me somehow for 12+ years. I have a 9P by the door that goes out with me and the dog each evening for the "walk" before bed. I also always have the mini-mag on my key chain.

In the cars are c-cell mag-lights and the wife's car has a 'twist to light' c-cell in the glove box too that's a great light but no brand name on it and has been around so long I don't remember where it came from. There’s a c-cell mag light on the bookshelf in the living room and I've got the old Safari Land Kel-Light (2 c-cells) from 1973 or so by the bed. Then there are several tin and plastic throw-a-way lights (all d-cell) around in the garage, kitchen and utility room. I also have Dad's old d-cell light with the magnet base attached to the furnace housing downstairs.
