The Kawasaki ZR750C Zephyr headlight bulb uses a 9003 size for both high and low beam functions. The replacement chart covers 1991 to 1993 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 Kawasaki ZR750C Zephyr uses the 9003 bulb across all listed model years (1991-1993) for both high beam and low beam headlight positions.
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 simultaneously.
The 9003 operates at 12 volts and carries a wattage rating of 60W on the high beam filament and 55W on the low beam filament.
The 9003 uses a P43t base, which is a standardized bayonet-style mount with a 43mm flange, and fitment depends on this base type matching the socket in the headlight housing.
The 9003 designation follows the ANSI standard used in the United States and Canada, and it is electrically and physically equivalent to the international HB2 designation.
Because the same bulb type fills both the high beam and low beam positions on the Kawasaki ZR750C Zephyr, a single replacement part number covers both headlight functions.
