The Piaggio MP3 500 headlight bulb size is H8 for both high and low beam applications. The replacement chart covers vehicle production spanning 2008 to 2014.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H8 is a single-filament halogen bulb operating at 12 volts and 35 watts, fitted with a PGJ19-1 base. It carries ECE certification, making it approved for use in Europe and most worldwide markets, as well as in the United States.
The Piaggio MP3 500 uses the H8 bulb for both its high beam and low beam headlight positions across the 2008-2014 model range.
Because both beam positions share the same H8 specification, the vehicle requires two bulbs of identical type for a full headlight replacement.
The PGJ19-1 base is a keyed single-pin connector specific to the H8 and a small number of related halogen types. Bulbs with physically similar but differently keyed bases, such as those in the broader PGJ19 family, are not interchangeable despite their outward resemblance.
The H8 single-filament design means each bulb serves only one lighting function. This contrasts with dual-filament types, where a single bulb handles two beam modes. Substituting a dual-filament bulb in an H8 socket is not a compatible replacement.
