OCTOBER PUZZLE CONTEST

There are three light switches up in the attic of an old house…  They control three light bulbs down in the basement.  The problem is that you don’t know which switch is connected to which bulb.  You can make one trip down to the basement to figure this out.
How are you going to do it?
Hint: Light bulbs that are “on” get hot.
