Why does the light bulb burn out when the lights are turned on in different rooms?

Hello! If you want to get an adequate answer, you should describe the problem in more detail:

1. Has it always been this way?
2. How long ago and after what began?
3. Or did you just install the wiring at all and faced such a problem?
4. What lamps burn out?
5. Do both lamps burn out without regularity in any of the rooms? Or does it burn out in the same room?
6. How is the wiring connected - everything is on the same line or on different ones, on the same phase or on different ones, a switch from one place or are they different switches?

If the wiring was installed a long time ago, but it started recently, then most likely when it is turned on, a short circuit occurs somewhere, from which a voltage surge occurs and the lamp burns out. The knockout machine also hints at this. Perhaps the insulation is damaged somewhere, maybe there is even a problem in the junction box, you need to check the quality of the connections.

If you just installed it, then check the connections, especially if the input is three-phase, suddenly you supply line voltage (380V) to the lamps.
