The Kawasaki ZX600 Ninja ZX-6 headlight bulb uses a 9003 size for both high beam and low beam functions. The replacement chart covers 1990 to 2002 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 ZX600 Ninja ZX-6 uses the 9003 bulb size for both high beam and low beam headlights across all model years from 1990-2002.
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.
The dual-filament construction of the 9003 allows a single bulb to serve both the high and low beam functions, which accounts for its use in both headlight positions on this motorcycle.
The 9003 bulb uses a P43t base, a bayonet-style mount with a 43mm collar, which determines physical fitment into the headlight housing.
The 9003 is functionally interchangeable with the H4 bulb type, as both share the same P43t base and dual-filament halogen configuration, though the 9003 designation follows ANSI standards while H4 follows ECE standards used in other markets.
Because the same bulb type is specified for both beam positions across the entire 1990-2002 production span, a single replacement bulb addresses both high and low beam requirements for any model year in this range.
