Additional Notes

The 1156 bulb is the sole low beam headlight type specified for the John Deere Gator CX 4x2 across the 2010-2015 model years.
The 1156 is a single-filament bulb, meaning it serves one lighting function only, as opposed to dual-filament types that handle two functions such as low and high beam within a single unit.
It operates on a 12-volt electrical system and draws 21 watts, which are standard ratings for this bulb type in automotive and utility vehicle applications.
The 1156 uses a BA15s bayonet base, a single-contact fitting where the bulb is inserted and rotated to lock into place, distinguishing it from pin-type or screw-base alternatives that are not compatible with this socket.
The 1156 designation follows ANSI standards recognized in the United States and Canada, confirming its specification within North American electrical and photometric norms.
The BA15s base of the 1156 is not interchangeable with the BA15d base found on dual-filament bulbs such as the 1157, despite the physical similarity between the two base styles.
