i was scratching my brain for this.let me give my guess.hope it will work out.first switch on the first switch.then wait for 5 min or so.now off the first one switch on the second one.go to the room and check wheather it is glowing or not.if it is glowing then it is easy.if it is not glowing then put your hands on the bulb.if it is hot then it is by the first switch.otherwise the third switch is the one which will be the right switch.Am i right?do reply for the post.
