Hi, I have recently moved into a new house (1920) it has been rewired in the past 5 yrs. I have recently found out that one of the light fittings that contains a low energy bulb (no encapsulated type) very faintly flashes (rhythmically) almost pulse like when switched off. I have tried another bulb but is does not do the same.
I have tried a mains tester and it glows again in a pulse like fashion but slower.
I do respect electricity, will do most diy jobs c ompetentlyand would welcome advice to see if the problem can be solved easily before contacting an electrician. The ceiling rose is on a ring main ?? and two way switching system.
