Arctic Cat EXT high beam and low beam headlight bulbs utilize 9003 and 9007 size specifications. The replacement chart covers vehicle production spanning 1991 to 1998.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Arctic Cat EXT uses two distinct bulb types across its headlight fitment history: the 9003 and the 9007, both of which are ANSI-standard dual-filament halogen bulbs rated at 12 volts.
The 9003 bulb carries a 60W/55W power rating, where the higher wattage serves the high beam filament and the lower wattage serves the low beam filament, all within a single housing using a P43t base.
The 9007 bulb operates on the same dual-filament principle but at a 65W/55W rating, drawing slightly more power on the high beam filament than the 9003, and it uses a PX29t base rather than a P43t base.
Because the 9003 and 9007 use different base types, P43t and PX29t respectively, the two bulbs are not interchangeable despite sharing a similar dual-filament halogen design.
For the Arctic Cat EXT, the 1996-1998 model years require the 9003 bulb for both high and low beam functions, with the same bulb serving both filament roles in a single unit.
The 1993-1995 model years require the 9007 bulb for both high and low beam functions, reflecting a different base and wattage configuration from the years immediately preceding and following that range.
The 1991-1992 model years return to the 9003 specification for both beam functions, meaning the 9007 fitment is isolated to the 1993-1995 production span.
