I have a light fixture in my garage, and when I put a normal
incandescent light bulb in it, I cannot reliable turn the light on.
That is, when I flick the switch to "on", I can see the bulb turn on
for a fraction of a second and then turn off, and stay off. If I
repeat this process a few times, the light will eventually stay on for
a few seconds, but then turn off again.

The fixture does not have a light sensor in it, and it was working
reliably for years until recently. Can anyone give me a clue as to
what's going on?

It could be the switch, the connection(s) at the switch, the wires
from the switch to the fixture, the connection(s) at the fixture, the
fixture itself or the bulb.

Doesn't anyone have any troubleshooting skills anymore?
