The Kawasaki VN750 Vulcan 750 headlight bulb uses a 9003 size for both high and low beam functions. The replacement chart covers vehicle production spanning 1986 to 2006 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 Kawasaki VN750 Vulcan 750 uses the 9003 bulb for both high beam and low beam headlight positions across the entire 1986-2006 production span.
The 9003 is a dual-filament halogen bulb, meaning a single unit contains separate filaments for both high and low beam functions, operating at 60W and 55W respectively.
The bulb operates on a 12V electrical system, which is standard for motorcycle applications of this type.
The 9003 carries the P43t base designation, a bayonet-style mount that determines physical fitment into the headlight housing.
The 9003 is an ANSI-standardized type recognized in the United States and Canada, and it is electrically and physically equivalent to the European H4 designation, which shares the same base, voltage, and wattage ratings.
Because the same 9003 bulb serves both the high beam and low beam positions, only one bulb type is required for the entire headlight assembly on this model.
