Main Plug potential corrosion

My main plug has potential corrosion and i think its the cause of my headlights flickering. My headlights that immediately start flickering but after around 50mins or so they begin to. Can any of you help? Also I don't think my headlight switch is the issue because I've had it replaced already.

That is indeed likely the cause of your headlight woes. Common problem. Get yourself a cheap little brass wire brush and some aerosol can electrical contact cleaner and go to town scrubbing that corrosion away!

To me it looks like a pin broke off and is stuck in the connector.

And wear eye protection.

You're going to have to re-pin that broken one.
