The Kia Spectra front side marker uses a 168 or 2357NA bulb size, while the rear side marker requires a 168 or 12961 bulb size. The replacement chart covers vehicle production years from 2000 to 2009 with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Kia Spectra uses the 168 bulb for both front and rear side marker positions across the 2007-2009 model years.
The 168 is an ANSI-standardized miniature wedge bulb in the T10 form factor, rated at 12V and 4.9W, and is recognized across the US and Canadian markets.
The 2357NA bulb serves the front side marker position on the 2000-2001 Kia Spectra, a notably different specification from the later model years.
The 2357NA is a dual-filament bulb with a BAY15d bayonet base and natural amber-tinted glass, rated at 12V with a dual-wattage output of 26.9W and 8W across its two filaments.
The natural amber glass of the 2357NA produces a color output without the use of a colored lens or housing, distinguishing it from clear-glass equivalents in the same bulb family.
The rear side marker on the 2001 Kia Spectra uses the 12961, a Philips-designated part, applicable to vehicles produced from May 22, 2001 onward.
The 12961 is a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W, sharing the same T10 form factor as the 168 but carrying a manufacturer-specific part number rather than an ANSI designation.
Although the 168 and 12961 share the T10 wedge form factor, the 168 is rated at 4.9W while the 12961 is rated at 5W, and their part number origins differ between ANSI standardization and Philips classification.
