The Kia Cadenza high beam headlight uses a 9005 bulb size while the low beam headlight requires an H7 bulb size. The replacement chart covers vehicle production years from 2017 to 2019 with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Kia Cadenza uses two distinct bulb types across its headlight system: the 9005 for high beam and the H7 for low beam, both applicable to the 2017-2019 model years equipped with halogen capsule headlamps.
The 9005 is a single-filament bulb operating at 65 watts, rated for high-intensity output and commonly used in dedicated high beam applications where a separate low beam bulb handles the opposing function.
The H7 is a single-filament halogen bulb typically rated at 55 watts, designed exclusively for low beam use. Its two-pin PX26d base is not interchangeable with the 9005, which uses a different three-pronged connector base.
Because the 9005 and H7 use physically incompatible bases, the high beam and low beam positions on the Kia Cadenza (2017-2019) with halogen capsule headlamps do not accept the same replacement bulb.
The halogen capsule headlamp condition applies uniformly across all three listed model years for both beam positions, meaning vehicles from this range equipped with non-halogen headlamp systems would reference different specifications.
