Additional Notes

The Buick Verano uses the 12961 bulb for the license plate position across all model years in the specification, spanning 2012-2017.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, which is one of the most widely used bulb types in automotive lighting applications.
The T10 designation refers to the bulb's tubular shape, with the number indicating its width in tenths of an inch, making it a compact light source suited to low-clearance housings such as license plate assemblies.
The base type on the 12961 is W2.1x9.5d, a wedge-style base that relies on tension from the socket rather than a bayonet or screw mechanism to maintain contact and retention.
The bulb operates at 12 volts and 5 watts, consistent with standard automotive electrical systems and typical of low-intensity illumination positions such as license plate lighting.
The T10 wedge format is shared by a broad range of bulbs from multiple manufacturers, meaning the 12961 Philips number represents one specific product within a larger interchangeable family, provided voltage and wattage ratings are matched.
When substituting bulbs in the T10 wedge category, the W2.1x9.5d base specification must be confirmed, as physically similar wedge bulbs can carry different base codes that affect socket fit and electrical contact.
