OK, in all fairness I know this has probably been addressed, but try searching for blinking lights on a Christmas forum.....
The interior lights in my house are blinking occasionally this year when I have a big show wide shimmer or blink going. It seems like they might have done this in years past as well, but this year I'm wondering what can cause that. Is it something I need to be concerned about? What are the possible culprits?
It seems like I read somewhere that it's possibly related to good/bad ground, but I can't remember now.
Thanks for the input.
