Arctic Cat Bearcat 340 high beam and low beam headlight bulbs utilize 9003 and 9007 bulb sizes for replacement specifications. The chart documents bulb size data spanning 1995 to 2000 production years.
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 operating at 12V with a 60W high beam filament and a 55W low beam filament. It uses a P43t base and conforms to the ANSI standard recognized in the United States and Canada.
The 9007 bulb is also a dual-filament halogen type rated at 12V, with a 65W high beam filament and a 55W low beam filament. It uses a PX29t base, which differs physically from the P43t base of the 9003.
Because the 9003 and 9007 use different base types, P43t and PX29t respectively, the two bulbs are not interchangeable despite both being dual-filament halogen units sharing the same low beam wattage.
The Arctic Cat Bearcat 340 used the 9007 bulb for both the high beam and low beam headlight positions in the 1995 model year.
From 1996-2000, the Bearcat 340 transitioned to the 9003 bulb for both headlight positions, representing a base type change from PX29t to P43t relative to the 1995 specification.
In all model years covered, both the high beam and low beam positions share a single bulb size, which is consistent with a single dual-filament unit serving both functions from one housing position.
