Additional Notes

The 894 bulb is the sole high beam headlight bulb type listed for the John Deere RSX850i, appearing across the 2013-2015 model years in the Projector Light Kit configuration.
The 894 is a single-filament halogen bulb, meaning it serves one lighting function only and does not combine high and low beam operation within a single unit.
It operates on a 12-volt electrical system and draws 37.5 watts, placing it in the lower wattage range typical of utility and off-road vehicle lighting applications.
The 894 uses a PGJ13 base, which is a specific pin-and-groove mounting type. Bulbs with different base configurations are not physically interchangeable with this socket, regardless of voltage or wattage similarity.
The 894 conforms to ANSI standards recognized in both the United States and Canada, indicating the bulb meets a defined set of dimensional and performance requirements within those markets.
The specification ties the 894 bulb directly to the Projector Light Kit, indicating this bulb size applies to that particular factory accessory configuration rather than to all possible lighting setups on the RSX850i.
