The Arctic Cat ZR 4000 uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production years spanning 2015 to 2017 with corresponding 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 the sole bulb type specified across all lighting positions for the Arctic Cat ZR 4000, covering both high beam and low beam headlight functions for the 2015-2017 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 60W for high beam output and one rated at 55W for low beam output.
Operating voltage for the 9003 is 12V, which is consistent with standard 12-volt automotive and powersports electrical systems.
The 9003 uses a P43t base, a bayonet-style mount with a 43mm flange that positions and locks the bulb within the headlight housing.
The 9003 designation follows the ANSI standard used in the United States and Canada. It is functionally equivalent to the European H4 bulb, and the two types are widely regarded as interchangeable in practice, though the designations originate from different regional standards bodies.
Because the 9003 serves both the high beam and low beam positions on the Arctic Cat ZR 4000, a single bulb failure affects both beam functions simultaneously, as both filaments reside within one unit.
