I have four wall mounted out door lights in the front of my home. A friend noticed that approximately every couple of minutes or so all the lights 'blink.' It is a quick blink however it is continuous and regular. I never noticed this before, do I have a problem, is it a short in the wiring, possibly one of the light fixtures that were changed last year has a problem?
Is this something that I should have looked at right away?
Thanks in advance.
