The Arctic Cat M8 uses the 894 bulb for high beam and the 893 bulb for low beam across all listed model years, spanning 2007-2011.
Both the 894 and 893 are ANSI-standardized halogen bulbs rated at 12 volts and 37.5 watts, each containing a single filament.
Although the 894 and 893 share identical voltage and wattage ratings, they are not interchangeable. The 894 uses a PGJ13 base, while the 893 uses a PGJ19 base, making the two physically incompatible with each other's sockets.
The PGJ13 and PGJ19 designations refer to prefocus base types, where the number indicates the nominal base width in millimeters. This difference in base size is the primary factor preventing cross-substitution between the high and low beam positions.
Single-filament construction means each bulb serves only one lighting function, which is why the Arctic Cat M8 requires two distinct bulb types rather than a single dual-filament unit to cover both beam positions.
Both bulb types conform to ANSI standards recognized in the United States and Canada, indicating consistent manufacturing tolerances and performance specifications within those markets.
