The Kawasaki ZRX1100 headlight bulb utilizes a 9003 size for both high and low beam functions. The replacement chart covers vehicle production spanning 1999 to 2000.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 is the most prominent bulb type in these specifications, serving both the high beam and low beam headlight positions across all listed years of the Kawasaki ZRX1100.
The 9003 is a dual-filament halogen bulb, meaning a single unit contains separate filaments for two distinct light output levels rather than requiring individual bulbs for each function.
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 standardized bayonet-style fitting that determines physical and electrical compatibility with a given socket.
The 9003 designation follows the ANSI standard applicable in the United States and Canada, distinguishing it from the functionally similar H4 bulb used under European ECE standards, which shares the same dual-filament halogen design but carries a different designation and may differ in base tolerances.
Because the high beam and low beam positions on the ZRX1100 for model years 1999-2000 share the same 9003 specification, both positions accept the same replacement bulb.
