The Kawasaki KLX650 headlight bulb uses a 9003 size for both high beam and low beam applications. The replacement chart covers 1993 to 1996 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 9003 bulb is the sole headlight bulb type specified across all listed years of the Kawasaki KLX650, covering both the high beam and low beam positions for 1993-1996.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 60W for high beam output and one rated at 55W for low beam output.
Because both the high beam and low beam positions share the same 9003 specification, a single bulb type serves both functions in the KLX650 headlight assembly.
The 9003 operates on a 12V electrical system and uses a P43t base, which is a bayonet-style mount with a 43mm flange used to secure and align the bulb within the housing.
The 9003 is defined under ANSI standards and is recognized in both the United States and Canada, distinguishing it from the functionally similar H4 bulb, which follows ECE standards used in other markets.
Although the 9003 and H4 share the same dual-filament halogen design and P43t base, they are not fully interchangeable in all applications due to differing beam pattern certifications between ANSI and ECE standards.
