The Moto Guzzi Nevada Classic 750 uses 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2004 through 2008 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 Moto Guzzi Nevada Classic 750 uses the 9003 bulb for both high beam and low beam headlight positions across the 2004-2008 model years.
The 9003 is an ANSI-standardized bulb designation recognized in the United States and Canada, making it a regionally defined specification rather than a universal global standard.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 60W for high beam output and one rated at 55W for low beam output.
The 9003 bulb operates on a 12-volt electrical system, which is consistent with standard motorcycle electrical architecture.
The 9003 uses a P43t base, a bayonet-style mount with a 43mm flange, which physically determines socket compatibility and is not interchangeable with other base types regardless of voltage or wattage similarity.
The 9003 is functionally equivalent to the H4 bulb used in international markets, though the designations originate from different standardization systems and packaging may differ between them.
Because the same 9003 bulb serves both the high beam and low beam positions, the Nevada Classic 750 uses a single-bulb headlight housing design rather than a separate-bulb arrangement for each function.
