Can't find this in the forum.....apologies if I am wrong!
House built 1970.
A few months ago I noticed a minor occasional 'blink' in the hall light. Since the darker nights began I noticed that the adjacent cloakroom light also began blinking - even though it was only on for a minute or two at a time. Eventually the cloakroom light began to blink so severly and permanently that I switched it off.
Tonight I noticed that the dining room light appears to have started blinking as well.
What is the likely cause?
All these lights/fittings are just 'ordinary' fittings. The only thing they have in common is that they are two-way switches.
How worried should I be? Is there anything we can do?
Thank you for any help
