The Moto Guzzi Griso 1200 uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2007 to 2018 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 bulb is the sole headlight bulb type specified for the Moto Guzzi Griso 1200, covering both high beam and low beam positions across the 2007-2018 model range.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments: one rated at 60W for high beam output and one rated at 55W for low beam output.
The 9003 operates on a 12V electrical system, which is standard for motorcycle applications of this type.
The 9003 uses a P43t base, a bayonet-style mount with a 43mm flange that positions and locks the bulb within the headlight housing.
The 9003 is defined under ANSI standards and is the designation used in the United States and Canada; it is electrically and physically equivalent to the H4 bulb designation used in international markets, and the two are generally interchangeable.
Because the 9003 serves both the high beam and low beam functions in a single unit, the Griso 1200 headlight assembly does not require separate bulbs for each beam mode across any of the listed model years.
