Why does the light in the apartment blink at night?
Hello! About a week ago, at about 1:00 a.m., a light began to flash in the kitchen, the first thought a light bulb burned out. But no. The light also blinked in the toilet. In the remaining rooms there are energy-saving lamps and they blinked only on one of the nights. The light in the refrigerator also flashes. The electrician called twice, they looked at something there and that’s all. They did not say anything sensible. The house is old, wiring too. It is interesting that the light begins to flash at about one in the morning and this continues until the morning. Once blinked in the afternoon. The neighbors are fine, the light does not blink in the entrance. What could be the problem?
Hello! And what neighbors did you ask? It is necessary to ask those who are connected to the same phase. There may be a bad contact somewhere either at your place or at the riser, and someone turns on powerful electrical appliances at night - that’s blinking. Yes, and the "blinking" concept loose.

It is likely that the cause of the blinking may be a switch with indicator key illumination (if the light is off). You have to either turn off the indicators, or solder (screw) a resistor or non-polar capacitor. I encountered this with the Legrand Etika series circuit breakers. What is most interesting is that later batches of the same model, the manufacturer himself began to add resistors to the circuit of indicators.
In fact, the resistor and capacitor are placed parallel to the lamp holder. 400V 0.1uF capacitor ...
