You are in a closed off room, completely bare, with one windowless door to an adjacent room. There is no way to see light of the second room.

There are three light switches on the wall in your room. They correspond to three standard light bulbs in the second room. You can flick any of the light switches any way you want.

Then you walk into the second room and you have to know which light switch corresponds to which light bulb.

How do you do it?
