Well, I had a different answer that I sent to the list, but it never came
through. It was so:
Turn on switch A. Go to the basement. Call 1 the bulb that is lighten, and
unplug it. So now we know switch A corresponds to bulb 1. Unplug also
another one that we will call 2. Go upstairs. Turn on switch B. If you see
light downstairs, switch B corresponds to bulb 3, and switch C to bulb 2.
Otherwise, it corresponds to bulb 2, and switch C to bulb 3. Of course you
should return to the basement to fix the bulbs you unplugged ;)
