Hi.
Some of the lights in my house are behaving strangely. One of them behaves normally when turned on but blinks rapidly on and off every four seconds when the light is switched *off* (a bit disturbing) and another one two floors below is just not working.
I will have to get a professional electrician in to help with this because I know nothing about the subject but what could be the explanation (particularly with the light that's on when it's off)?
Eq.
