The Arctic Cat ProClimb uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production years spanning 2012 to 2013.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 is a dual-filament halogen bulb operating at 12 volts, with a high beam output of 60 watts and a low beam output of 55 watts. It uses a P43t base and conforms to the ANSI standard recognized in the United States and Canada.
Because the 9003 carries two filaments within a single bulb, it serves both the high beam and low beam functions from one unit. The Arctic Cat ProClimb (2012-2013) relies on this single bulb type across both headlight positions rather than separate bulbs for each function.
The P43t base is a bayonet-style fitting with a 43mm collar, and correct base alignment is a factor in fitment. A bulb with a different base type would not seat properly in the ProClimb headlight socket regardless of voltage or wattage compatibility.
The 9003 and H4 bulb types share the same P43t base and dual-filament configuration, though they originate from different standardization systems. The 9003 follows the ANSI designation used in North America, while H4 follows the ECE designation used in Europe. Physical interchangeability between the two types varies by application and socket design.
