Switchs and light bulb.
 
Have a go at this one.

3 switchs in a room match 3 light bulbs in another room.
You cannot see from one room to the other.

Solution
 
You turn on switch 1 for a minute, then turn it off. Quickly turn on switch 2 and go to the room with the bulbs.

The bulb that is off, but hot is operated by switch 1.

The blub that is on is operated by the switch 2.

The blub that is off and cold is operated by switch 3.

Really? Thanks.
 
It is original thought, but it's second hand original thought.

I heard a similar one, about 1 lightbulb and 3 switches a while ago. I answered that one on my own and applied that solution to this one.

Thanks.
