The Argo 8x8 HD uses 894 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2011 through 2016 production years with corresponding bulb size specifications.
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 for the Argo 8x8 HD, covering 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 higher operating temperatures and longer service life compared to standard incandescent bulbs.
The 894 bulb operates at 12 volts and draws 37.5 watts, placing it in the low-wattage range of automotive halogen bulbs.
The 894 uses a PGJ13 base, a pin-type connector with a 13mm spacing between pins, which is a relatively uncommon base type in automotive applications and limits direct interchangeability with more widely used bases such as H4 or H11.
The 894 conforms to ANSI standards recognized in both the United States and Canada, indicating the bulb meets regulated performance and safety criteria in those markets.
Both the high beam and low beam positions on the Argo 8x8 HD use the same 894 bulb specification across all six model years listed, meaning a single bulb type serves both functions rather than separate bulbs for each beam.
Because the 894 is a single-filament bulb, each beam function requires its own dedicated bulb housing rather than a dual-filament arrangement where one bulb handles both beams.
