The two bulb types specified for the Arctic Cat Prowler XT headlight system are the 9008 and the 881, both of which conform to ANSI standards recognized in the United States and Canada.
The 9008 is a dual-filament halogen bulb rated at 12V with a wattage split of 65W for high beam and 55W for low beam, and it uses a P26t base. Its dual-filament construction allows a single bulb to serve both high and low beam functions within one housing.
The 881 is a single-filament halogen bulb rated at 12V and 27W, fitted with a PGJ13 base. Because it carries only one filament, it is dedicated to a single lighting function rather than switching between two output levels.
The P26t and PGJ13 bases used by the 9008 and 881 respectively are physically incompatible with each other, meaning the two bulb types are not interchangeable despite both operating on a 12V system.
For the 2015 and 2017 model years, the Prowler XT specifies the 9008 exclusively across both high beam and low beam positions.
The 2016 model year lists both the 9008 and the 881 for both beam positions, indicating that two distinct headlight configurations were used within that single production year.
The 881 bulb was the specified fitment for both high beam and low beam positions across the 2006-2014 model years, with the exception of 2008, and excluding 2015 onward where the 9008 took over.
The lower wattage of the 881 at 27W compared to the 9008's 65W high beam output reflects a meaningful difference in power draw, a factor relevant to the vehicle's electrical load when replacing or cross-referencing bulbs between model years.
