Kawasaki ZR650 Z650 headlight bulbs utilize a 9003 size for both high beam and low beam functions. The replacement chart covers 2017 to 2018 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 listed across all headlight positions for the Kawasaki ZR650 Z650, covering both the high beam and low beam functions for the 2017-2018 model years.
The 9003 is a dual-filament halogen bulb, meaning a single physical unit contains separate filaments for two distinct output levels rather than requiring two separate bulbs.
The bulb 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 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, which defines the bulb's electrical and mechanical specifications within those markets.
Because the same 9003 bulb serves both the high beam and low beam positions on the ZR650 Z650, the two headlight circuits draw from the same physical lamp unit rather than separate dedicated bulbs.
