The Kawasaki KAF820 Mule PRO-FX headlight bulb uses 9003 and 9008 sizes for both high and low beam functions. The replacement chart covers 2016 through 2022 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 and 9008 are both ANSI-standard dual-filament halogen bulbs rated at 12 volts, meaning each physically contains two filaments within a single housing to serve both high and low beam functions from one bulb position.
The 9003 operates at 60 watts on high beam and 55 watts on low beam, while the 9008 operates at 65 watts on high beam and 55 watts on low beam, sharing the same low beam wattage but differing on high beam output.
The 9003 uses a P43t base and the 9008 uses a P26t base, making the two bulb types physically incompatible with each other despite their similar dual-filament halogen construction.
The Kawasaki KAF820 Mule PRO-FX used the 9008 bulb for both high and low beam headlights across the 2016-2019 model years.
The 2021-2022 model years of the KAF820 Mule PRO-FX use the 9003 bulb for both high and low beam positions, representing a different base type than earlier models.
Because the 9003 and 9008 carry different base types, a bulb sourced for a 2016-2019 model is not a direct physical fit for a 2021-2022 model, and vice versa.
Both the 9003 and 9008 specifications apply to the US and Canadian markets under ANSI standardization, which governs the electrical and physical characteristics of each bulb type.
