The Kia Soul front side marker uses a 12961 or 168 bulb size, while the rear side marker requires a 2357 bulb size for replacement. The chart contains specifications covering 2010 through 2024 model years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Kia Soul front side marker uses the 168 bulb across 2010-2023, making it the most consistently specified bulb in these listings. It is an ANSI-standard miniature wedge bulb rated at 12V and 4.9W with a T10 form factor.
For the 2024 Kia Soul, the front side marker shifts to the 12961 bulb, a Philips part number rather than an ANSI designation. Although it shares the T10 wedge form factor with the 168, it carries a W2.1x9.5d base designation and is rated at 5W rather than 4.9W.
Because the 12961 and 168 share the T10 wedge form factor, they are physically similar, but the 12961 is a manufacturer-specific part number while the 168 is an industry-wide ANSI standard. Substitution between the two warrants attention to base compatibility and wattage tolerance.
The rear side marker on the Kia Soul uses the 2357 bulb across all listed model years, 2010-2019. This is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with filaments drawing 26.9W and 8W respectively.
The 2357 is noted as a brighter variant of the 1157 bulb. Both share the BAY15d bayonet base, which means the 2357 and 1157 are physically interchangeable, though the 2357 produces higher output on its primary filament.
From 2014-2019, the rear side marker specification for the Kia Soul includes a conditional note restricting the 2357 fitment to trims without projector-type headlamps. No alternative bulb size is listed for projector-headlamp trims within the rear side marker sub-part.
The front and rear side markers on the Kia Soul use entirely different bulb families. The front positions use a wedge-base T10 bulb, while the rear positions use a dual-filament bayonet-base bulb. The two types are not interchangeable.
