The Kawasaki ZN1100B LTD headlight bulb uses a 9003 size for both high and low beam functions. The replacement chart covers 1984 to 1985 production specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb is the sole bulb type listed across all headlight positions for the Kawasaki ZN1100B LTD, covering both the high beam and low beam functions for the 1984-1985 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 60 watts for high beam output and one rated at 55 watts for low beam output.
Because the 9003 serves both beam functions in this application, the high beam and low beam headlight positions use an identical bulb, making the two positions interchangeable with respect to the bulb itself.
The 9003 operates on a 12-volt electrical system, which is standard for motorcycles of this type.
The bulb uses a P43t base, a standardized bayonet-style fitting that determines physical compatibility with the headlight housing.
The 9003 designation follows the ANSI standard used in the United States and Canada, distinguishing it from the functionally similar H4 bulb used under European standards, which shares the same dual-filament halogen design but carries a different designation.
