Additional Notes

The H8 is a single-filament halogen bulb operating at 12 volts and 35 watts, fitted with a PGJ19-1 base. It follows the ECE standard, which is recognized across Europe and numerous other markets worldwide, and also carries approval for use in the United States.
The Arctic Cat Bearcat 570 XT uses the H8 bulb for the high beam headlight across the 2009-2014 model years.
Because the H8 is a single-filament design, it serves only one lighting function per bulb. This distinguishes it from dual-filament bulbs, which handle two functions within a single housing.
The PGJ19-1 base is specific to the H8 and is not shared with several other common halogen types. Substituting a bulb with a different base type would result in an incompatible fit in the headlight socket.
The H8 belongs to a family of physically similar ECE halogen bulbs that includes the H9 and H11, all of which share a comparable form but differ in wattage and are not interchangeable despite their visual resemblance.
