Additional Notes

The 2007 Kia Spectra uses bulb 12961 for the courtesy light, though this applies only to vehicles produced up to July 1, 2007.
The 12961 is a Philips part number designation for a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W.
The 168 is an ANSI standard designation recognized across the US and Canada, also a T10 miniature wedge bulb rated at 12V and 4.9W.
Both the 12961 and 168 share the T10 wedge form factor, though the 12961 carries a specific W2.1x9.5d base classification while the 168 is defined under the broader ANSI standardization system.
The 2005-2006 Kia Spectra uses the 168 bulb for the courtesy light position.
The wattage difference between the two bulb types is minimal, with the 12961 rated at 5W and the 168 at 4.9W, both operating on a 12V circuit.
Because the 12961 carries a manufacturer-specific base designation and the 168 follows an ANSI standard, substitution between the two warrants verification of base compatibility before fitment.
