Arctic Cat 450 Headlight Bulb Size

Arctic Cat 450 headlight bulbs utilize HS1 size specifications, with high beam applications requiring 880 bulbs and low beam applications requiring 899 bulbs. The replacement chart covers 2011 through 2015 production years with corresponding bulb size data.

Additional Notes

The HS1 bulb is the most frequently specified type across the Arctic Cat 450 headlight data, appearing in both high beam and low beam positions for the 2014-2015 model years.
The HS1 follows the ECE standard, which governs lighting regulations in Europe and much of the world. It is a dual-filament halogen bulb rated at 12V with a 35W/35W output and uses a PX43t base.
Because the HS1 carries two filaments within a single bulb, it is capable of serving both high and low beam functions from one unit, which accounts for its use in both positions on the 2014-2015 Arctic Cat 450.
The 2011 Arctic Cat 450 uses different bulb types for each beam position: the 880 for high beam and the 899 for low beam, both conforming to the ANSI standard used in the United States and Canada.
The 880 and 899 are each single-filament halogen bulbs, meaning each handles only one lighting function. Despite their similar ANSI classification, they are not interchangeable due to differing base types and wattage ratings.
The 880 uses a PG13 base and is rated at 27W, while the 899 uses a PGJ13 base and is rated at 37.5W. The base designations indicate physically distinct socket configurations that prevent cross-installation.
The HS1 and the 880 or 899 bulbs operate under different international standards, ECE versus ANSI respectively, and have incompatible base types, making substitution between the 2011 and 2014-2015 fitments not possible.
