A series of three lights, the last in the chain I think can be on one minute and when a switch is used all thre die. No fuse or circuit switch pops.
It is sporradic. It appears suddenly.Any single or two of the three lights will be on , the third added and they pop. Not all three need to be on and they pop.
Having gone off, they, 1, 2, 3 come on agin as they wish.
This has appeared suddenly. No electricl changes, lights, switches have been made.
Do you mean by pop the lights blowing, Most faults occur at the assessories, you say no circuits have been altered. So something is shorting across. Have a look in the ceiling roses for loose connection.
