light dilemma

Your in a room that has three lightbulbs hanging from the ceiling, these lightbulbs are conrolled by three swithes in the room next door, each switch controlling one of the bulbs.

You are allowed to leave the room only ONCE, but you can flick the swithes in the next room as many times as you like and then re enter the other room (you cannot see the lightbulbs from the room with switches in).

Your mission is to find out which swith controls which lightbulb!! How would you do this??????

Easily enough, just turn two of the light switches on. Wait a while, and then turn one of them off, then quickly enter the room. One light will be on, one off, and one off but still hot.
