Just wanted to throw this one out there. As we all know, the replacement of the headlight bulbs is a lot more involved and timeconsuming than it needs to be. I just burned through my 3rd bulb and the bike is just about to turn 25K km, with the last being a Philips heavy duty bulb made specifically for motorcycles.
I tried one of the myriad of Chinese dogsh!t LED bulb specials, and it failed in about a month and stuck out the back of the headlight housing and thus the dust covers couldn't be used..
Anyway, to cut the story short I just installed a 2nd gen OSRAM headlight bulb (see link) and fits the MP3 perfectly. No fans to fail and the rubber dust cover fits with room to spare.
And to boot, it's made in Italy and comes with a 5 year warranty so that's bound to be a winner.
The only downside is that only the low beam bulb fits due to the weird design by Piaggio of the high beam socket.
