re: Flickering Lights in fixtures

Had the same problem with some light fixtures after switching to LED. Turn off the breaker to the fixtures,take the bulb out, get a small flathead screwdriver, stick it between the ceramic and metal of the light socket, then slightly bend the metal in around the socket. Do Not Bend It Much. The goal is to just snug the socket up against the the bulb some.

An electrician told me to do this when I had the issue and it fixed the problem. Worth a try before calling someone.
