Arctic Cat Norseman 6000 ES high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart covers 2018-2019 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 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.
The Arctic Cat Norseman 6000 ES uses the 9003 bulb for both the high beam and low beam headlight positions across the 2018-2019 model years.
Because the 9003 contains two filaments within a single housing, one filament serves the high beam function and the other serves the low beam function, allowing a single bulb to fulfill both headlight roles simultaneously.
The P43t base is a bayonet-style fitting with a 43mm collar, and correct base matching is necessary for proper installation, as physically similar bulbs with different base types are not interchangeable in this application.
The 9003 and H4 bulbs share the same dual-filament halogen design and P43t base, making them functionally equivalent in many applications. However, fitment compatibility depends on the specific socket and housing configuration of the vehicle.
