Kia Rondo front and rear side marker bulbs both utilize a 168 size bulb for proper illumination. The replacement chart covers 2007 through 2010 model years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Kia Rondo uses the 168 bulb for both front and rear side marker positions across the 2007-2010 model years.
The 168 is a miniature wedge-type bulb, classified under the T10 form factor, which refers to its tubular shape with a wedge base that connects without a separate metal socket pin.
The 168 bulb operates at 12 volts with a power draw of 4.9 watts, placing it in the low-wattage range typical of marker and clearance lighting applications.
The 168 designation follows ANSI standardization, meaning the bulb conforms to a defined specification recognized across the United States and Canada.
Because the same bulb size applies to all four side marker positions on the Kia Rondo, a single bulb type serves the entire side marker system on the vehicle.
The T10 wedge base format is shared by several bulb numbers, including the 194 and 147, though these carry different wattage ratings and are not direct substitutes for the 168 without confirming electrical compatibility.
