The Piaggio BV Tourer 500 high beam and low beam headlight bulbs both utilize a 9003 size. The replacement chart covers vehicle production years spanning 2007 to 2010.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Piaggio BV Tourer 500 uses the 9003 bulb across both the high beam and low beam headlight positions for the 2007-2010 model years.
The 9003 is an ANSI-standardized bulb designation used in the United States and Canada, making it a North American market specification.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments to serve both high and low beam functions within one unit.
The bulb operates on a 12-volt electrical system and draws 60 watts on the high beam filament and 55 watts on the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange. This base type is shared with the H4 bulb, and the 9003 and H4 are functionally interchangeable in most applications, though the 9003 designation is specific to the ANSI standard while H4 follows the ECE standard used in Europe.
Because the same 9003 bulb serves both the high beam and low beam positions on the Piaggio BV Tourer 500, the vehicle relies on a single bulb per headlight assembly rather than separate bulbs for each function.
