Three light bulbs and three switches. Identify each switch with its bulb!

Posted on June 12th, 2009 by Sandeep in Puzzle

There is a room with a door (closed) and three light bulbs (initially switched off). Outside the room there are three switches, connected to the bulbs. You may manipulate the switches as you wish, but once you open the door you can’t change them. Identify each switch with its bulb.

Switches : S1,S2 and S3
Bulbs : B1, B2 and B3
