All the light bulbs are switched off.
How do you find out which switch operaters which light bulb without taking the bulbs off and only go down to the room below once?

Answer
Leave the first switch off. Turn on the second one and leave it on for a while. Then turn off the second switch and turn on the third switch. Go downstairs. The light that is on goes to the third switch, the light that is off but warm goes to the second switch, and the light that is off but cold goes to the first switch.
At least, that's one way to do it.
Answer
^^yea...
Answer
it's kinda like what AiLing said but a little different.
you turn on the first one, leave it on for a little bit then turn it off and turn on the second one and go down stairs. the warm one is the first one, the one that's on is the second one and the third one is the cold one.
