I'll second the torch in every pocket. I use a head torch, one of the ones that you can flick between red and white LED's, I carry spare batteries for it and the small mag light I keep in my pocket (not in your flight bag, you don't want to be fiddling about in the dark looking for something by touch). I did mine in a PA28 for the simple reason that it has the best instrument lighting of any of our club a/c.
