The Kia K900 high beam headlight uses a 9005 bulb size while the low beam headlight requires a D3S bulb size. The replacement chart covers vehicle production years spanning 2015 to 2017 with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
ECE standard (Europe & worldwide). Mercury-free HID (xenon) discharge bulb with PK32d-5 base and integral ignitor, for projector-type housings. 42V, 35W.
The D3S is a discharge bulb type used in high-intensity discharge (HID) lighting systems. It operates without an internal igniter, meaning it relies on an external igniter built into the ballast assembly. The D3S designation also indicates the bulb contains no mercury, which aligns with environmental regulations adopted in automotive manufacturing during the mid-2000s.
The Kia K900 uses the D3S bulb for the low beam headlight position across the 2015-2017 model years, and this fitment is conditional on the vehicle being equipped with HID headlamps.
The 9005 bulb serves the high beam headlight position on the K900 for the same 2015-2017 span, also under the HID headlamp condition. The 9005 is a halogen bulb operating at 65 watts with a single filament, and it belongs to the P20d base family standardized by the Society of Automotive Engineers.
The combination of a D3S low beam and a 9005 high beam reflects a bi-lamp HID system, where the discharge bulb handles the primary low beam output and a conventional halogen bulb provides the high beam function separately, rather than a projector system that switches a single bulb between modes.
The D3S and 9005 are not interchangeable with each other. They occupy different sockets, operate on different electrical principles, and serve distinct optical functions within the headlamp housing.
The D3S bulb is not cross-compatible with D1S or D2S bulbs despite sharing a similar discharge technology. The D3S uses a different base configuration that physically prevents installation in sockets designed for D1S or D2S fitments, making socket type a critical factor in replacement.
