The Kawasaki KLX230R uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2021 to 2022 model 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 a dual-filament halogen type, meaning a single bulb contains two separate filaments: one rated at 60W for high beam operation and one rated at 55W for low beam operation.
The 9003 designation follows the ANSI standard used in the United States and Canada, making it a regionally standardized specification rather than a universal global format.
The Kawasaki KLX230R uses the 9003 bulb for both the high beam and low beam headlight positions across the 2021-2022 model years, with a single bulb type serving both lighting functions simultaneously.
The 9003 bulb operates on a 12V electrical system, which is consistent with standard 12-volt motorcycle electrical architecture.
The P43t base is the physical mounting interface of the 9003 bulb. This base type is a bayonet-style fitting with a 43mm cap, and it determines physical compatibility with the headlight housing.
Because the 9003 serves as both the high beam and low beam bulb on the KLX230R, the two filaments within a single unit are switched independently by the vehicle's lighting circuit rather than using separate bulbs for each function.
