Additional Notes

The H11 is a single-filament halogen bulb operating at 12 volts and 55 watts, fitted with a PGJ19-2 base. It follows the ECE standard, which governs lighting regulations across Europe and numerous other markets worldwide, and also carries approval for use in the United States.
The Arctic Cat Z1 uses the H11 bulb for the high beam headlight across the 2009-2011 model years.
Because the H11 is a single-filament design, it handles only one lighting function per bulb. Vehicles that require separate bulbs for high and low beam rely on this single-filament configuration rather than a dual-filament alternative such as the H4.
The PGJ19-2 base is specific to the H11 and is not interchangeable with the physically similar H8 or H9 bases, even though those bulbs share the same general housing shape. Substituting a bulb with a different base designation risks improper seating and incorrect light output.
