The Kawasaki ZX1000 Ninja 1000R headlight bulb uses a 9003 size for both high beam and low beam applications. The replacement chart covers 1986 to 1987 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 9003 is the sole bulb type across all listed positions and years in these specifications, serving both high beam and low beam headlight functions in the Kawasaki ZX1000 Ninja 1000R for 1986-1987.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 60W for high beam output and one at 55W for low beam output.
Operating voltage for the 9003 is 12V, consistent with standard automotive and motorcycle electrical systems of that era.
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 applicable to the United States and Canada, which defines the bulb's electrical and optical performance requirements.
Because the 9003 handles both high and low beam duties through its dual filaments, the Kawasaki ZX1000 Ninja 1000R (1986-1987) uses a single bulb per headlight position rather than separate bulbs for each function.
The H4 bulb is the international equivalent of the 9003 and shares the same dual-filament configuration and P43t base, though the 9003 and H4 designations reflect different regional standards and may carry minor performance tolerances that affect direct interchangeability.
