Hyundai Kona Electric front fog light uses H8 bulb size while rear fog light requires 12088 bulb size. The replacement bulb size chart covers 2019 to 2020 production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Hyundai Kona Electric uses the H8 bulb for front fog lights across the 2019-2020 model years.
The H8 is a single-filament halogen bulb rated at 12V and 35W, fitted with a PGJ19-1 base, and classified under ECE standards with approval also recognized in the United States.
The rear fog lights on the 2019-2020 Kona Electric take the 12088 bulb, which is a Sylvania OEM part number corresponding to the ANSI 1156 standard bulb.
The 1156 (12088) is a single-filament bulb rated at 12V and 21W, mounted via a BA15s bayonet base, a base type that is not interchangeable with the PGJ19-1 base used by the H8.
Because the H8 and 1156 use entirely different base designs, front and rear fog light bulbs for the Kona Electric are not interchangeable with each other.
The H8 belongs to a family of halogen capsule bulbs that includes the H9 and H11, which share a similar physical form but differ in wattage and base orientation, making cross-substitution inadvisable without confirming base compatibility.
