The Kawasaki ZX750F Ninja 750R headlight bulb uses a 9003 size for both high and low beam functions. The replacement chart covers 1987 to 1990 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 9003 bulb is an ANSI-standard halogen type recognized in the United States and Canada, operating at 12 volts with a dual-filament design rated at 60 watts for high beam and 55 watts for low beam.
The P43t base is a three-tab bayonet-style mount, which physically locks the bulb into position and ensures correct filament alignment within the reflector housing.
The Kawasaki ZX750F Ninja 750R uses the 9003 bulb size across both the high beam and low beam headlight positions for the 1987-1990 model years.
Because both beam positions share the same 9003 bulb, a single dual-filament unit serves both functions rather than requiring two separate single-filament bulbs.
The 9003 and H4 bulb types share the same P43t base and dual-filament configuration, though 9003 reflects the ANSI designation while H4 reflects the ECE designation used in other markets.
