Flickering light, question

[Andrassy]

So a light bulb we have outside that has not been working for a very long time. I've actually never seen it work, as when we moved into this place it wasn't working. That was 3+ years ago.

So today, just now in fact, suddenly this light started flickering. I turned it off. I don't understand how this could've happened. Does anyone have any idea about why this happened? I just found it very weird, and I'm asking here because I have no experience on the subject.

I'll turn it on and see if it starts doing it again.

Thank you people.
