The Arctic Cat F6 EFI high beam headlight uses two distinct bulb types across its model years: the 894 for 2007-2009 and the H11 for 2010-2011.
The H11 is a single-filament halogen bulb operating at 12V and 55W, built to the ECE standard used in Europe and worldwide, with a PGJ19-2 base. It also carries approval for use in the United States.
The 894 is a single-filament halogen bulb operating at 12V and 37.5W, built to the ANSI standard used in the US and Canada, with a PGJ13 base.
The H11 and 894 draw on different wattage ratings, 55W and 37.5W respectively, which reflects a meaningful difference in power consumption and light output between the two bulb types.
The H11 and 894 use different base types, PGJ19-2 and PGJ13 respectively, meaning the two bulbs are not physically interchangeable despite both being single-filament halogen types rated at 12V.
The low beam headlight on the Arctic Cat F6 EFI uses the 894 bulb for 2007-2009, the same type specified for the high beam during those same years.
For the 2010-2011 model years, only the high beam headlight bulb size is listed in the specifications, with no low beam entry present for those years.
Because the H11 and 894 share neither base type nor wattage, substituting one for the other would require a socket adapter at minimum and could affect electrical load on the vehicle's lighting circuit.
