The Kawasaki ZX750 Ninja ZX-7 headlight bulb uses a 9003 size for both high beam and low beam functions. The replacement chart covers 1989 to 2003 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 Kawasaki ZX750 Ninja ZX-7 uses the 9003 bulb size for both the high beam and low beam headlight positions across all model years from 1989-2003.
The 9003 is an ANSI-standardized bulb type recognized 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 output.
Because the 9003 carries a dual-filament construction, a single physical bulb serves both the high and low beam functions, which accounts for the identical part number appearing across both headlight positions in the specifications.
The 9003 bulb uses a P43t base, a bayonet-style mount with a 43mm collar, which determines physical fitment into the headlight housing and is not interchangeable with single-filament bases such as the H1 or H7.
The 9003 is electrically and physically equivalent to the H4 bulb used in international markets, though the designations differ by regional standards body; both share the same base type, wattage ratings, and filament configuration.
The consistent use of the 9003 specification across the entire 1989-2003 production span of the ZX750 Ninja ZX-7 means a single bulb type covers all model years without variation between positions or years.
