Bulbs

Imagine you are in a room with 3 switches. In an adjacent room there are 3 bulbs (let's say in lamps which are on a regular table), each switch belongs to one bulb. All are off at the moment. It is impossible to see from one room to another. No help from anybody else is allowed. How can you find out which switch belongs to which bulb, if you may enter the room with the bulbs only once?

You break two of the bulbs then you will know...

Well how will you know which switch turned on which of those light bulbs?

When you go into the room with the lamps, bring them into the room with the switches.
