3 Light Switch Puzzle Tee

There are three light switches (labeled 1, 2 and 3) outside a room with a closed door. Inside the room are three incandescent light bulbs, one per switch. You may flip the switches as much as you like before opening the door, but once you have opened it you may no longer flip any of the switches. The light bulbs do not make any noise. How can you determine which switch controls which bulb?
