Headlight bulb removal.

[TCBOB]

Hi there. I have 1 of 4 Maxsym400i s registered in New Zealand. All were privately imported from Australia as I understand it. Mine certainly was.
There are Sym dealers here but dont carry spares for mine and are not particularly helpful but that's ok. I get me spares off Aliexpress and most common consumables are easy to get.
I recently hit a large pothole and now my headlight doesn't work on high or low beam.
Has anyone replaced a headlight bulb and if so what is the procedure?
I was just reading about the seat and windscreen adjustments. My seat is ok but previous owner put a clip on extra screen which made the screen vibrate and flex over bumps. I removed it and the screen is far more stable. I'd like to try raising the screen but the black cover looks like it's been glued in places!
I got the bike in 2020 with 16000kms. It took 2yrs to get it registered ( speedo didnt work and finally sourced an ABS sensor from England) Now it has done 32000kms and goes really well.
Regards from NZ. Tony.
