Hyundai Kona Headlight Bulb Size

Additional Notes

• The two bulb types present across all Hyundai Kona headlight specifications are the 9005 and H7, both of which are single-filament halogen bulbs operating at 12 volts.
• The 9005 follows the ANSI standard used in the United States and Canada, draws 65 watts, and uses a P20d base, while the H7 follows the ECE standard with a PX26d base and draws 55 watts.
• Because the 9005 and H7 use physically different base types, P20d and PX26d respectively, the two bulbs are not interchangeable without an adapter.
• The Hyundai Kona used the H7 bulb for both high and low beam positions in the 2018-2019 model years, with the 2018 specification noting this applies to vehicles equipped with halogen capsule headlamps.
• The 2020 Kona also specifies the H7 for both beam positions, again with the halogen capsule headlamp condition noted, indicating that not all 2020 units share the same headlamp configuration.
• The 2021 model year carries two separate bulb specifications for both the high and low beam positions: the 9005 for vehicles produced up to March 8, 2021, and the H7 for those produced after that date, reflecting a mid-year production change.
• The 2022-2023 Kona specifies the 9005 for both high and low beam positions, representing a shift away from the H7 that was standard in earlier production.
• The high beam and low beam specifications are identical across all listed years, meaning the Kona does not use a separate bulb type for each function in any of the configurations shown.
• The H7 bulb, while rooted in the ECE regulatory framework, carries approval for use in the United States and Japan as well, making it a globally accepted fitment.
• The 10-watt difference between the 9005 at 65 watts and the H7 at 55 watts means vehicles transitioning between the two specifications, such as across the 2021 production change, are not drawing equivalent power through the headlamp circuit.
