The Arctic Cat ZL 550 uses the 894 bulb for high beam and the 885 bulb for low beam across the 2000-2003 model years.
Both the 894 and 885 are ANSI-standardized halogen bulbs recognized in the United States and Canada, meaning they conform to a defined set of performance and dimensional criteria rather than being proprietary specifications.
Both bulb types use a single filament, which means each bulb handles only one lighting function, explaining why the ZL 550 requires separate bulbs for high and low beam operation.
Both the 894 and 885 share the same PGJ13 base type, a prefocused base design that positions the filament at a fixed point relative to the reflector to maintain consistent light output.
Both bulbs operate on a 12-volt electrical system, which is consistent with the standard voltage used in most powersport and automotive applications.
The low beam 885 bulb is rated at 50 watts, while the high beam 894 is rated at 37.5 watts, making the low beam the higher-wattage unit of the two.
Although the 894 and 885 share the same PGJ13 base, their wattage ratings differ, and the two types are not interchangeable despite the physical base compatibility.
