Honda Motorcycle VF750C Magna uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1988 to 2003 model year specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Honda Motorcycle VF750C Magna uses the 9003 bulb size for both the high beam and low beam headlight positions across all listed model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both the high beam and low beam functions simultaneously.
The 9003 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 bulb uses a P43t base, which is a bayonet-style mount with a 43mm flange, and this base type determines physical fitment into the headlight housing.
The 9003 designation follows the ANSI standard recognized in the United States and Canada, making it a regionally standardized specification rather than a proprietary or manufacturer-specific size.
The 9003 bulb is functionally equivalent to the H4 bulb used under European ECE standards; however, the two designations reflect different regulatory frameworks, and substitution between them warrants attention to base and housing compatibility.
The same 9003 specification applies to both headlight positions across the 1988 and 1994-2003 model years of the VF750C Magna, indicating no variation in bulb fitment between those positions throughout the listed production span.
