I've been reading up on replacement headlights for my 1980 P200 and this one https://www.scootermercato.com/Scooter-Parts/Headlight-Assemblies/582946 with this bulb https://www.scootermercato.com/Scooter-Parts/Bulbs/H435-35 seems to be a pretty straight forward swap for the stock P200 bulb.
The Scooter Mercato listing says "Easy retrofit for older models". What does that mean and has anyone had any "surprises" installing one of these?
Does anyone have any recommendations for something better?
