The Argo 6x6 HD uses 894 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production spanning 2011 to 2016.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 894 bulb is the sole bulb type specified across all headlight positions in the Argo 6x6 HD for model years 2011-2016.
The 894 is a single-filament halogen bulb, meaning it contains one tungsten filament enclosed in a halogen gas-filled capsule, which allows for a higher operating temperature and longer service life compared to standard incandescent bulbs.
The 894 operates at 12 volts and draws 37.5 watts, placing it in the low-wattage range for halogen headlight bulbs.
The 894 uses a PGJ13 base, a pin-type connector with a 13mm pin gap, which is a relatively uncommon base type and limits direct interchangeability with more widely used headlight bulb families such as H4 or H7.
The 894 conforms to ANSI standards recognized in both the United States and Canada, indicating the bulb meets defined photometric and dimensional criteria established by the American National Standards Institute.
Because the Argo 6x6 HD uses the same 894 bulb for both high beam and low beam positions across all six model years in the specifications, beam switching is not achieved through a dual-filament bulb but rather through a separate lighting circuit or mechanical arrangement.
