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 Bearcat Z1 XT uses the H11 bulb for the high beam headlight across the 2009-2014 model years.
Because the H11 is a single-filament design, it handles only one lighting function per bulb. Bulbs with dual filaments, such as the H4, are not interchangeable with it despite superficial similarities in physical form.
The PGJ19-2 base is specific to the H11 and is not shared by closely related types such as the H8 or H9, even though those bulbs share the same general housing shape. Substituting a bulb with a different base designation risks improper seating and potential electrical incompatibility.
