Kawasaki ZX1200 Ninja ZX-12R high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart contains vehicle production years and bulb size specifications spanning 2000 to 2005.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Kawasaki ZX1200 Ninja ZX-12R uses the 9003 bulb size across all documented model years (2000-2005) for both high beam and low beam headlight positions.
The 9003 is an ANSI-standard designation recognized in the United States and Canada, making it the North American equivalent of the internationally designated H4 bulb.
This bulb type is a dual-filament halogen unit, meaning a single bulb serves both the high and low beam functions through two separate filaments housed within one glass envelope.
The 9003 operates on a 12-volt electrical system and carries a wattage rating of 60W on the high beam filament and 55W on the low beam filament.
The base type is P43t, a standardized bayonet-style fitting with a 43mm flange, which physically determines socket compatibility and must match the housing for proper installation.
Because both the high beam and low beam positions share the same 9003 specification across the entire 2000-2005 production run, a single bulb type covers all headlight replacements for the ZX1200 Ninja ZX-12R without position-specific differentiation.
