The Kawasaki ZG1000 Concours headlight bulb uses a 9003 size for both high and low beam functions. The replacement chart covers vehicle production spanning 1986 to 2006.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Kawasaki ZG1000 Concours uses the 9003 bulb for both the high beam and low beam headlight positions across all model years from 1986-2006.
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 9003 operates on a 12-volt electrical system and draws 60 watts on the high beam filament and 55 watts on the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange. This base type determines physical fitment into the headlight housing and is not interchangeable with other base configurations.
The 9003 designation follows the ANSI standard used in the United States and Canada. It is electrically and functionally equivalent to the H4 bulb used under international ECE standards, though housing fitment compatibility depends on the specific base and retaining ring design of the motorcycle.
