The Moto Guzzi V11 Sport uses 9003 bulb size for both high beam and low beam headlight applications. This replacement chart covers 2000 to 2001 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 is a dual-filament halogen bulb operating at 12 volts, with a 60-watt filament for high beam and a 55-watt filament for low beam, mounted on a P43t base.
The P43t base designation refers to a bayonet-style base with a 43mm flange, a standardized fitting used across a range of halogen headlight applications.
The Moto Guzzi V11 Sport uses the 9003 bulb for both high beam and low beam headlights across the 2000-2001 model years.
Because a single 9003 bulb serves both beam functions through its dual filaments, the high beam and low beam positions in the V11 Sport share the same physical bulb rather than requiring separate units.
The 9003 is classified under the ANSI standard and is the designation used in the United States and Canada. It is electrically and physically equivalent to the international HB2 designation, which means bulbs sold under either name are interchangeable in practice.
The H4 bulb, common in many European and Asian markets, shares the same dual-filament halogen construction and P43t base as the 9003, making it a widely recognized cross-reference for this fitment.
