You find yourself in a locked room. What would you need to get out?

There are three light bulbs in a room, and three light switches outside the room. You are outside, and want to match up which switch goes with which light bulb. You can only travel into the room once, and cannot come back in again. You can do anything you want upon entering the room. How can you set the situation so that you will know which switch goes with which light bulb?

Turn 2 on. Go into the room, I now know the first one (the one that's off). Break one of the bulbs that are on. Walk out. Turn off one of the 2 that were on. If the light goes off under the door then it belongs to the one I didn't break. If nothing happens, then it belongs to the one I did break.
