I carry a UK Mini Q4 (4*AA) LED ligh in my BC pocket on pretty much all my dives. For night/wreck/other dark stuff dives I carry a UK C8 (4*C-cell) LED light as my primary.
Tank lights like glow sticks or strobes can be handy, especially if theres different colors on different people as it makes it a bit easier to distinguish eachother under water in the dark. If youre just two people diving (or PADI forbid, youre solo) it might not be of THAT much use unless you lose or have both/all the lights crap out on you and your buddy need to find someone swimming around in the dark with no light source..
