The Kawasaki Z1000 headlight bulb size specifications indicate that both high beam and low beam applications utilize an H7 bulb size. The replacement chart covers vehicle production years spanning 2003 to 2013.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H7 is the sole bulb type specified across all listed model years of the Kawasaki Z1000, covering both the high beam and low beam headlight positions throughout the 2003-2013 range (excluding 2009).
The H7 is a single-filament halogen bulb, which means separate bulbs are required for the high beam and low beam functions rather than a single dual-filament unit handling both.
H7 bulbs operate on a 12V electrical system and carry a 55W power rating, placing them within the standard halogen output range used widely in motorcycle and passenger vehicle headlight applications.
The H7 uses a PX26d base, a two-pin bayonet-style connector that is specific to this bulb type and is not interchangeable with other common bases such as the P43t used by H4 bulbs.
The H7 is rated under the ECE standard, which governs lighting regulations across Europe and many other markets worldwide, and the bulb also carries approval for use in the United States and Japan.
Because the high beam and low beam positions on the Z1000 both call for the H7, the same bulb part number serves both sockets, though each position requires its own individual unit.
