Moto Guzzi V7 headlight bulbs utilize a 9003 size for both high beam and low beam applications. The replacement chart covers 2008 to 2018 production specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Moto Guzzi V7 uses the 9003 bulb type for both high beam and low beam headlight positions across the 2008-2018 model years.
The 9003 is an ANSI-standardized bulb designation used in the United States and Canada, operating on a 12-volt electrical system with a dual-filament halogen design rated at 60 watts for high beam and 55 watts for low beam.
The dual-filament construction of the 9003 means a single bulb unit serves both beam functions, which accounts for its use in both the high beam and low beam positions on the V7.
The 9003 bulb uses a P43t base, a bayonet-style mount with a 43mm cap width, which determines physical fitment into the headlight housing.
The 9003 standard is functionally equivalent to the H4 designation used in international markets, though the two designations originate from different standardization systems and packaging may differ.
Because the same bulb type fills both beam positions, a single replacement part number applies to the entire headlight assembly of the V7 throughout the listed model range.
