Additional Notes

The Jeep Liberty uses two different license plate bulb sizes across its model years, with the 168 fitted to 2002-2006 models and the 12961 fitted to 2008-2012 models.
Both the 168 and the 12961 are T10 miniature wedge bulbs, meaning they share the same T10 envelope form factor despite carrying different part designations.
The 12961 is a Philips part number rather than an ANSI industry-standard designation, and it specifies a W2.1x9.5d wedge base at 12V and 5W.
The 168 is an ANSI-standardized bulb recognized across the United States and Canada, rated at 12V and 4.9W.
The two bulbs differ slightly in wattage, with the 12961 drawing 5W and the 168 drawing 4.9W, a difference of 0.1W.
Although both bulbs share the T10 form factor, the 12961 carries a manufacturer-specific base designation (W2.1x9.5d), which is a detail not formally expressed in the ANSI 168 specification.
The 2007 Jeep Liberty model year is not represented in the specifications, so no bulb size is attributed to it.
