switch on one of the three switches and wait for 30 seconds.Then off the earlier switch and on another one. Go into the room with bulbs.if one of the 3 bulbs is lights,then 2nd switch you on is the switch of that bulb.If no lights then check the bulbs if one of them i shot or not.If one of them is hot because it was light, then 1st switch you have on the switch of that bulb.
