The Arctic Cat XF uses the 9003 bulb size for both high beam and low beam headlights across the 2014-2019 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both the high and low beam functions within one housing.
The 9003 operates at 12 volts and carries a wattage rating of 60W on the high beam filament and 55W on the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange. This base type determines physical fitment into the headlight socket and is not interchangeable with other base configurations.
The 9003 designation follows the ANSI standard used in the United States and Canada. It is functionally equivalent to the H4 bulb used under international IEC standards, though the designations originate from different standardization bodies and packaging may differ.
Because the same 9003 bulb serves both beam positions, a single replacement bulb type covers the full headlight assembly on the Arctic Cat XF across all listed model years.
