There are two rooms, one with 3 light switches and one with 3 lights. Your task is to solve which switch goes to which light given the following parameters:

- You begin in the room with the switches, which are all off by default, then you enter the second room with the lights. Once you leave either room, you cannot go back.

- You can turn the switches on or off before leaving the first room. (No, you cannot put the switches at midway points - it's a binary choice.)

- From either room, you cannot see the state of the other room in any way.

Go!

*Note: Don't write the answer plainly if you know it, either effectively hide it from those who wouldn't want to see it or talk outside the post.
