Kia Soul Headlight Bulb Size

Additional Notes

• The 9008 bulb is a dual-filament halogen type rated at 12V with a high/low wattage split of 65W and 55W, using a P26t base. Its dual-filament design allows it to serve both high and low beam functions within a single bulb, which is why it appears across both headlight positions in the Kia Soul specifications for 2014-2019.
• The 9003 bulb is also a dual-filament halogen type, rated at 12V with a 60W/55W split and a P43t base. It is the designated bulb for both high and low beam positions on the 2010 and 2011 Soul.
• The 9005 is a single-filament halogen bulb rated at 12V and 65W with a P20d base. On the 2022 Soul, it is listed for both the high beam and low beam positions, meaning each function uses a separate, dedicated bulb rather than a shared dual-filament unit.
• The H7 is a single-filament halogen bulb operating at 12V and 55W with a PX26d base. It follows the ECE standard but holds approval in the US and Japan as well. On the 2014-2019 Soul, it is specified for projector-type headlamp configurations in both beam positions.
• The D3S is a mercury-free HID xenon discharge bulb rated at 42V and 35W, with a PK32d-5 base and an integral ignitor. Its significantly higher operating voltage relative to the halogen types in these specifications reflects the nature of high-intensity discharge technology, which requires a high-voltage arc to produce light rather than a heated filament.
• The D3S is specified exclusively for low beam use on the 2014-2019 Soul when equipped with HID headlamps. No corresponding HID bulb is listed for the high beam position on those same years, where H7 or 9008 halogen types are used instead depending on headlamp configuration.
• On the Kia Soul for model years 2014-2019, headlamp configuration directly determines bulb fitment. Vehicles without projector-type headlamps use the 9008, while those with projector-type headlamps use the H7 for halogen setups or the D3S for HID setups in the low beam position.
• The 9005 and 9008 follow the ANSI standard applicable to the US and Canada, while the H7 and D3S follow the ECE standard used in Europe and internationally. The presence of both standards across the Soul's model year range reflects regional and trim-level variation in headlamp system design.
• The P26t base of the 9008 and the P20d base of the 9005 are physically distinct and not interchangeable, despite both being ANSI-standard halogen bulbs operating at 12V. Substituting one for the other is not supported by these specifications.
• The D3S integral ignitor is a built-in component of the bulb itself, distinguishing it from older HID bulb types that rely on a separate external ignitor. This design characteristic is relevant to replacement procedures, as the ignitor is replaced along with the bulb rather than independently.
