P3D Re: Where does NASA get flashbulbs?

[Bob Wier <wier@xxxxxxxxxxxxxxxxx>]

I was watching a program on lightning tonight on either the Discovery
Channel or the Learning channel (I forget which). Anyway, they were talking
about the elaborate lightning precautions around the lanuch pad for the
shuttle in Florida. Over the top of the gantry there is a 1" diameter stainless
steel rope which runs down a thousand feet on either side and is grounded.
They way they tell if they've had a strike is that they have an "old
fashioned flash bulb" attached which will blow if sufficient charge
arcs over. 

Question: where do you suppose NASA gets it's flash bulbs? It looked like
one of the minature bayonet types.
