Kia Cadenza Fog Light Bulb Size

The Kia Cadenza fog light requires a 9006 bulb size for the lighting system. Data for the specific bulb requirements covers the range from 2017 to 2018.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The Kia Cadenza front fog light specifications list two distinct bulb types across the 2017-2019 model years: the H8 and the 9006, both single-filament halogen bulbs operating on a 12V system.
The H8 follows the ECE standard, which governs lighting regulations across Europe and much of the world, though it also carries approval for use in the United States. It uses a PGJ19-1 base and draws 35W.
The 9006 follows the ANSI standard, the North American regulatory framework covering the US and Canada. It uses a P22d base and draws 55W, making it a notably higher-wattage bulb than the H8.
The H8 fitment on the Kia Cadenza is conditional, applying only to vehicles equipped with Halogen Capsule Headlamps. This trim-level dependency means the H8 and 9006 are not interchangeable across all configurations of the same model year.
For the 2017 and 2018 model years, both the H8 and 9006 are listed as valid front fog light sizes, each corresponding to a different headlamp configuration on the vehicle.
The 2019 model year lists only the H8, and only for vehicles with Halogen Capsule Headlamps, indicating a single specified fog light bulb for that year.
The PGJ19-1 base of the H8 and the P22d base of the 9006 are physically incompatible with each other, so the two bulb types cannot be substituted for one another regardless of wattage or voltage similarities.
