Additional Notes

The 2007 Kia Spectra5 uses a 12961 bulb for the courtesy light, while the 2005-2006 model years use a 168 bulb.
Both the 12961 and 168 are T10 miniature wedge bulbs, meaning they share the same physical envelope profile.
The 12961 is a Philips part number designation, whereas the 168 is an ANSI standard designation used across the US and Canada.
Both bulbs operate at 12 volts, consistent with standard automotive electrical systems.
The 12961 is rated at 5W, and the 168 is rated at 4.9W, placing them within 0.1W of each other in power draw.
The 12961 carries a W2.1x9.5d base specification, which defines the contact pin width and spacing of the wedge base.
Despite the shared T10 form factor, the 12961 and 168 carry different part designations and should not be assumed to be interchangeable without confirming base compatibility for the specific model year.
