Help with a little bitty light

I need a teeny dive light that I can clip to my BC and use at night to see the settings on my strobe and to read my computer. I dive with a fairly large DSLR rig with one or two focus lights and two strobes and my dive computer is attached to my housing. During the day, all is fine, but at night I need to be able to see my strobe settings and to occasionally confirm that I have at least some air left.

Any ideas on a teeny light sufficient for looking at gauges at night that will run for a relatively long time.

thanks
Bill

How about this: http://www.leisurepro.com/p-ptca1c/princeton-tec-amp-1-led-flashlight-with-cone

You might need to put a frosted filter on it, as it might be too bright!

Edit: Oh, there's one included!

That might work OK, but it is a bit bigger than I want.

Pelican has several itty bitty lights that run on coin cells

Edit - never mind, they are not dive rated.

I know, I have flooded a few. I was hoping to find something like

but waterproof.
So far no joy.
