Additional Notes

The 168 bulb is the sole dome light bulb type listed for the Kubota RTV-X1100C across the 2015-2018 model years.
The 168 bulb follows the ANSI standard, which is the recognized classification system for miniature bulbs in the United States and Canada.
It is a T10 miniature wedge bulb, meaning it uses a wedge-style base rather than a bayonet or screw fitting, and the T10 designation refers to a tubular envelope that is 10/8 inches wide.
The bulb operates at 12 volts, consistent with the standard electrical systems found in utility vehicles of this type.
Its rated power draw is 4.9 watts, placing it in the low-wattage range typical of interior dome lighting applications.
The wedge base design of the 168 bulb means it is held in place by the socket contacts gripping the base directly, with no separate metal cap or pin.
The T10 wedge form factor is shared by several bulb numbers, so substitution with a physically similar bulb does not guarantee electrical compatibility unless the voltage and wattage ratings also match.
