Additional Notes

The 894 bulb is the sole low beam headlight fitment for the John Deere Gator TH 6x4 across the 2010-2016 model years.
The 894 is a single-filament halogen bulb, meaning it serves one lighting function only and does not combine low and high beam operation within a single unit.
It operates at 12 volts and draws 37.5 watts, placing it in the lower wattage range typical of utility and work vehicle lighting applications.
The 894 uses a PGJ13 base, a pin-type locating base that physically prevents substitution with bulbs using incompatible base types, such as the more common H-series bases found in passenger vehicles.
The 894 designation follows the ANSI standard recognized in both the United States and Canada, meaning the bulb conforms to a defined set of electrical and physical parameters shared across compliant manufacturers.
Because the PGJ13 base is specific to a narrow range of bulb types, replacement options are limited to bulbs that share both the base type and the 12V/37.5W electrical rating.
