The Kawasaki ZX1000 Ninja ZX-10 high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart covers 1988 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 Kawasaki ZX1000 Ninja ZX-10 uses the 9003 bulb for both high beam and low beam headlight positions across the 1988-1990 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments: one rated at 60W for high beam output and one rated at 55W for low beam output.
Because both the high beam and low beam positions share the same 9003 specification, a single bulb type serves both functions in the headlight assembly.
The 9003 bulb operates on a 12V electrical system and uses a P43t base, which is a bayonet-style fitting with a 43mm collar.
The 9003 designation follows the ANSI standard used in the United States and Canada, distinguishing it from the functionally similar H4 bulb, which follows European ECE standards and uses the same P43t base but carries a different designation.
The P43t base is not interchangeable with other common base types such as the P14.5s used on single-filament halogen bulbs, making base compatibility a relevant factor when sourcing a replacement.
