We moved to a bungallow some months ago, it's not new, some 40years old. Problem is that we are having to renew light bulbs on a regular basis. Bulbs in standard lamps, wall lights and porch lights, dont seem to last much more than 3 weeks. I have used an earth tester on all wall sockets and test proved OK. The lights do dim on occaisions, but it's not a regular thing. The bulbs we use are not the cheap variety. Can anyone shed any light on this problem.
Cheers
