The light bulb in one of the ceiling lights (at the top of the stairs) just
went "bang" and the glass section blew off leaving the metal part still in
the fitting. The bulb was burnt looking along one side.
Can anyone suggest what might have caused this? I took the light fitting
apart and all the connections are intact and there is no sign of any short
circuiting. The fitting is old, but I can't see any problem. I put in a
new bult and everything seems fine.
Earlier today I re-wired another light fitting (at the bottom of the stairs)
because the wiring in that one had come apart and was no longer working.
This is on a different fuse circuit from the one that blew, although they do
share a double light switch. Is it likely to be a coincidence that this one
blew so soon after?
I am not an electrician (even an amateur one) so any advice would be
