The Kawasaki ZG1400 Concours uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production spanning 2008 to 2022 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 is the sole bulb type specified across all headlight positions for the Kawasaki ZG1400 Concours, covering both high beam and low beam functions for the 2008-2022 model years.
The 9003 is a dual-filament halogen bulb, meaning a single physical bulb contains two separate filaments: one rated at 60 watts for high beam output and one rated at 55 watts for low beam output.
The 9003 operates on a 12-volt electrical system and uses a P43t base, which is a bayonet-style mount with a 43mm collar width.
The 9003 designation follows the ANSI standard used in the United States and Canada. It is electrically and physically equivalent to the H4 bulb used under European and international standards, and the two are generally considered interchangeable.
Because the 9003 serves both the high beam and low beam positions on the ZG1400 Concours, both functions are housed within the same bulb unit rather than in separate single-filament bulbs.
The P43t base is a keyed fitting, meaning the bulb is designed to seat in only one rotational orientation, which ensures correct filament alignment within the headlight reflector housing.
