The Kia Soul EV uses the 168 bulb for its license plate lighting across the 2015-2019 model years.
The 168 is classified as a miniature wedge bulb, following the T10 form factor, which refers to a tubular bulb body approximately 10mm wide with a wedge-style base that connects without a separate metal socket pin.
The 168 operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of license plate and courtesy lighting applications.
The 168 designation follows ANSI standardization, meaning the bulb conforms to a defined specification recognized across the United States and Canada.
The T10 wedge base design is shared by several bulb types within the miniature wedge family, which can create interchangeability considerations when selecting a replacement, as physical fit alone does not confirm electrical compatibility.
A replacement bulb must match the 12V, 4.9W electrical rating of the 168 to avoid potential issues with brightness or electrical load on the vehicle's lighting circuit.
