I have a wall light switch that powers two sconce lights in my living room.
One of the sconce lights stopped working. My first thought is that it was just a dead bulb but the same bulb works elsewhere and a new bulb doesn't work in the non-working sconce.
None of the circuit breakers have tripped.
Is the most likely cause a severed wire or wire that has come unattached? If that is the case, is it possibly dangerous?
