Why do the lights in the chandelier flash when the light is off?
The other day there was a power surge, after that in the room, when the light is off, all the lamps in the chandelier blink (LED lamps). What to do?
Have the lamps been turned on? It can be anything, starting from problems with wiring and ending with a switch. Illuminated switch? If yes, then you can try to disconnect it from the wiring and see if it remains blinking or not, if it remains, then somewhere there is a leak past the switch.
