loosen screw on cover and light comes back on?
Just wondering if this is a problem or if I am just being rather paranoid (which I tend to be when it comes to electricity). I have a flush ceiling fixture on my front porch which stopped working last night. I assumed it was the bulbs, as they have been in there for several years so I just went out to change them. I had to remove the bottom cover of the fixture in order to get to the bulbs, and as I was unscrewing the third screw the light came back on. It appears to be working fine now; I shut it on and off several times. But does this indicate a loose wire or something? Not much evidence to go on, I know, but it seems strange to me that just loosening a screw a couple of times would affect the fixture. Thanks for any suggestions.
