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 governs lighting regulations across Europe and many other markets worldwide, and also carries approval for use in the United States.
The Arctic Cat Bearcat 570 uses the H8 bulb for its high beam headlight across the 2010-2014 model years.
The PGJ19-1 base is a keyed, push-and-twist type fitting. Bulbs sharing a similar appearance but carrying a different base designation within the PGJ19 family, such as PGJ19-2 or PGJ19-3, are not interchangeable with the H8 despite their physical resemblance.
At 35 watts, the H8 sits at a lower wattage than many other halogen types in the H-series family. Substituting a higher-wattage bulb of a different designation risks exceeding the thermal and electrical tolerances of the original socket and wiring.
Because the H8 is a single-filament bulb, it serves only one lighting function per unit. It is not designed to handle both high and low beam duties from a single housing position.
