I believe the correct question is?:  
There are three light bulbs in the room and three switches in the 
basement and which switch controls which light bulb.
The solution should be found without using any tools 
or special devices and no ones help with one trip to the basement.
You can enter the room as many times as you wish. 

I will post the answer later.
