Additional Notes

The 2357 bulb is an ANSI-standard dual-filament type with a BAY15d bayonet base, rated at 12V with filaments drawing 26.9W and 8W respectively. The higher-wattage filament serves the brake function, while the lower-wattage filament handles the tail light function.
The Kia Soul uses the 2357 as its primary brake bulb across the majority of listed model years, spanning 2010-2011 and 2014-2023, making it the dominant fitment in these specifications.
The 2357 is described as a brighter variant of the 1157, meaning the two share the same BAY15d bayonet base and are physically interchangeable in many applications, though their wattage ratings differ.
The 2020 Kia Soul brake bulb specification calls for a P21/5W rather than a 2357. Although both bulbs share the BAY15d bayonet base, the P21/5W follows the ECE standard used in European and worldwide markets, and its filament wattages of 21W and 5W differ from those of the 2357, so the two are not direct equivalents despite the shared base type.
The center high mount stop light across 2022-2024 uses the 12961, a Philips-designated T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. This is a single-filament bulb suited only to on/off stop light duty.
The 168 bulb, used in the center high mount stop light for 2010-2011 and 2014-2019, is also a T10 miniature wedge type rated at 12V and 4.9W. Its ANSI designation and wattage differ slightly from the 12961, and the two are not confirmed interchangeable within these specifications.
For model years 2014-2019, both the brake bulb and center high mount stop light specifications carry a "Without Projector-Type Headlamps" or "Without Projector Headlamps" qualifier, indicating that the listed bulb sizes apply only to vehicles not equipped with that headlamp configuration.
