Arctic Cat Bearcat XT high beam and low beam headlight bulbs both use 9003 size bulbs. The replacement chart covers 2018 to 2019 vehicle production years with bulb size specifications.
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, meaning a single bulb contains two separate filaments to produce both high and low beam output from one unit.
The 9003 operates at 12 volts, with the high beam filament rated at 60 watts and the low beam filament rated at 55 watts.
The Arctic Cat Bearcat XT uses the 9003 bulb for both the high beam and low beam headlight positions across the 2018-2019 model years.
Because the high and low beam positions share the same bulb type, a single 9003 bulb serves both functions rather than requiring separate bulbs for each beam.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm collar, and only bulbs with this base are physically compatible with the socket.
The 9003 is defined under ANSI standards and is recognized in both the United States and Canada, making it a widely available specification in North American markets.
The 9003 and H4 bulbs share the same dual-filament halogen design and P43t base, though they originate from different standardization bodies, ANSI and ECE respectively, and are generally considered interchangeable in practice.
