Additional Notes

The Lincoln LS license plate bulb specifications cover model years 2000-2006, with two distinct bulb sizes used across that span.
The 2005-2006 Lincoln LS uses the 168 bulb, an ANSI-standardized miniature wedge type rated at 12V and 4.9W.
The 168 bulb follows the T10 wedge form factor, a common miniature bulb format recognized under both US and Canadian standards.
The 2000-2004 Lincoln LS uses the 12961, a Philips part number designation for a miniature wedge bulb rated at 12V and 5W.
The 12961 also follows the T10 form factor and uses a W2.1x9.5d base, which is the standard pin configuration for that wedge type.
Both the 168 and 12961 share the T10 wedge form factor and operate at 12V, though they differ slightly in wattage, at 4.9W and 5W respectively.
Despite the physical and electrical similarities between the two bulbs, the split in specified part numbers across model years indicates they are not treated as interchangeable in these fitment records.
The 12961 is a manufacturer-specific part number rather than an ANSI industry code, meaning sourcing it may depend on Philips-compatible product lines rather than a universal standard reference.
