The Kawasaki KAF820 Mule PRO-FXT headlight bulb uses 9008 and 9003 sizes for both high and low beam functions. Replacement chart data spans 2015 to 2023 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 Kawasaki KAF820 Mule PRO-FXT uses two distinct bulb types across its model years for both high beam and low beam headlights: the 9008 and the 9003, both of which are ANSI-standard dual-filament halogen bulbs rated at 12 volts.
The 9008 bulb carries wattage ratings of 65W for high beam and 55W for low beam, while the 9003 operates at 60W for high beam and 55W for low beam, making the two types similar in low beam output but divergent at high beam.
A key physical difference between the two bulb types is the base configuration. The 9008 uses a P26t base, whereas the 9003 uses a P43t base, meaning the two are not physically interchangeable despite their similar electrical ratings.
For the 2015-2019 model years (excluding 2020), the KAF820 Mule PRO-FXT specifies the 9008 bulb for both high beam and low beam positions.
The 2021-2022 model years specify the 9003 bulb for both beam positions, representing a different base type than the surrounding model years.
The 2023 model year returns to the 9008 specification for both beam positions, the same type used across the 2015-2019 range.
Because the 9008 and 9003 differ in base type, a bulb sourced for a 2021-2022 vehicle would not fit the socket of a 2015-2019 or 2023 vehicle, and vice versa, making year-specific verification essential before replacement.
Both the high beam and low beam positions share the same bulb specification within any given model year, indicating the KAF820 Mule PRO-FXT uses a single dual-filament bulb to serve both functions rather than separate single-filament bulbs for each.
