The Kawasaki ZX1100 Ninja ZX-11 headlight bulb uses a 9003 size for both high beam and low beam functions. The replacement chart covers 1990 to 2001 model 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 ZX1100 Ninja ZX-11 uses the 9003 bulb size for both high beam and low beam headlight positions across all model years from 1990-2001.
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 within one housing.
The bulb operates on a 12-volt electrical system and carries a wattage rating of 60W on the high beam filament and 55W on the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm collar, and this base type determines physical fitment into the headlight housing.
The 9003 designation follows the ANSI standard used in the United States and Canada, and it is electrically and physically equivalent to the European H4 bulb type, though packaging and labeling may differ by market.
Because the same 9003 bulb size applies to both the high beam and low beam positions across the entire 1990-2001 production run of the Kawasaki ZX1100 Ninja ZX-11, there is no variation in bulb fitment between those two functions or across those model years.
