Arctic Cat Bearcat 550 high beam and low beam headlight bulbs utilize 9003 and 9007 sizes. The replacement chart covers 1995 to 1996 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Arctic Cat Bearcat 550 uses two distinct bulb types across its 1995 and 1996 model years: the 9003 and the 9007, both of which are ANSI-standard dual-filament halogen bulbs rated at 12 volts.
The 9003 bulb, fitted to the 1996 Arctic Cat Bearcat 550, operates at 60W on high beam and 55W on low beam, and uses a P43t base.
The 9007 bulb, used in the 1995 model, draws 65W on high beam and 55W on low beam, and uses a PX29t base, which is physically distinct from the P43t base of the 9003.
Because the 9003 and 9007 use different base types, the two bulbs are not interchangeable despite sharing the same low beam wattage of 55W.
Both the 9003 and 9007 serve the high beam and low beam functions within a single bulb unit, made possible by their dual-filament construction.
The same bulb size applies to both the high beam and low beam headlight positions for each respective model year, indicating a single-bulb system handles both functions per headlight assembly.
