The Kawasaki ZR900 Z900 headlight bulb utilizes an H7 size for both high beam and low beam functions. The replacement chart covers 2017 through 2019 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 H7 is the sole bulb type across all listed headlight positions for the Kawasaki ZR900 Z900, covering both high beam and low beam functions for the 2017-2019 model years.
The H7 is a single-filament halogen bulb, meaning each lamp housing requires a dedicated bulb for each beam function rather than a dual-filament unit serving both roles from a single source.
H7 bulbs use a PX26d base, a two-pin connector with a locking collar that is not interchangeable with other common bases such as H4 or H11.
The H7 operates at 12 volts and 55 watts, which are standard ratings for this type in halogen automotive lighting applications.
The H7 specification originates from the ECE (Economic Commission for Europe) regulatory standard and carries approval for use in Europe, the United States, and Japan, giving it broad international fitment validity.
Because both the high beam and low beam positions share the same H7 specification on the ZR900 Z900, the same bulb part number is applicable to either socket, though the sockets themselves remain physically separate housings.
