Nissan Micra K11 - K11 Micra main beam dash indication - starfield

The question I have is about the main beam warning light that I get on the dash board.
When the lights are set to 'main beam' (brightest setting), the blue headlamp symbol on the dash is lit which is normal.
When the lights are set to 'dipped', I still get the blue headlamp symbol on the dash which is not normal.
The actual headlamps themselves work OK, it's just the dash indication that seems wrong to me.
This electrical issue just started yesterday.

Having done some research, I have located the problem:

The plug at the back of the o/s headlight has partially melted. I tried to salvage what was left of it in order to get it working. It worked again as good as before. (Ideally I should have replaced the melted plug).

I hope this will be useful to anybody with similar problems
