I got a batch of LED bulbs which have been working well until now. Some of these are having an issue. Let me describe the issue. A bulb start to flicker after while and if I try it on another socket, it works just fine. So that makes me think it is the original socket. So I go ahead and try another bulb on the original socket and that bulbs works just fine as well.
So for some reason, the original bulb flickers on the original socket only – but both the bulb and socket seem to work with other socket and bulb. This has been happening with a few bulbs. What could the problem be? Could it be the base of the bulb s of bad quality so it creates some sort of reaction with the socket so those two cannot work well anymore. I have no idea and I am out of ideas.
PLEASE HELP! Thank you.

Notice that the base of an LED bulb (the part above the socket) is wider than the base of an incandescent. Often, something about the fixture is making contact with the wider LED bulb, so that it binds up and prevents it from screwing into the socket all the way. It feels like it's screwed in all the way, but it's not.
If you look at the nub on the bottom of bulb or socket, you may see arcing marks.
