The Kia Sedona side marker requires a unique 12961 bulb size for the lighting assembly. Data for the specific component covers the range from 2018 through 2018.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 168 bulb is the most frequently specified size across the Kia Sedona's front side marker positions, covering model years 2006-2012 and 2018. It is an ANSI-standard miniature wedge bulb in the T10 form factor, rated at 12V and 4.9W.
The 2357 bulb is the most frequently specified size across the rear side marker positions, appearing in every rear side marker entry from 2002-2014. It is a dual-filament ANSI-standard bulb with a BAY15d bayonet base, rated at 12V with filaments drawing 26.9W and 8W respectively.
The 12961 is a Philips-branded part number rather than an ANSI standard designation. It is a miniature wedge bulb in the T10 form factor with a W2.1x9.5d base, rated at 12V and 5W, and it serves both the front and rear side marker positions on the 2021 Kia Sedona.
For the 2019-2020 Kia Sedona, the 12961 bulb applies to both front and rear side marker positions only on vehicles equipped with halogen capsule headlamps, indicating that this fitment is trim- or package-dependent rather than universal across the model year.
The front and rear side marker positions do not always share the same bulb size. The 2006-2012 and 2018 model years use the single-filament 168 at the front while the rear requires the dual-filament 2357, making the two positions non-interchangeable during those years.
The 1034NA is a natural amber glass variant of the 1157 bulb family, fitted with a BAY15d bayonet base and dual filaments rated at 12V, 21W and 5W. Its amber glass construction is integral to the bulb itself rather than dependent on a colored lens, and it appears exclusively in the front side marker position on the 2002-2005 Sedona.
The BAY15d bayonet base used by both the 1034NA and the 2357 features two offset pins that prevent incorrect insertion. Although both bulbs share this base type, their wattage ratings differ substantially, and the two are not listed as interchangeable within these specifications.
The T10 wedge base shared by the 168 and the 12961 is a common form factor, but the two bulbs carry different designations and originate from different standards bodies. The 168 is an ANSI-standard part, while the 12961 is a Philips catalog number, and the specifications treat them as distinct fitments across different model years.
