Additional Notes

The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor. It uses a W2.1x9.5d base, which is a wedge-style base that requires no locking mechanism, relying instead on tension from the socket to hold the bulb in place. The electrical rating is 12 volts at 5 watts.
The Nissan Sentra uses the 12961 bulb for its cornering light position across the 2021-2023 model years.
The T10 designation refers to the bulb's tubular envelope, with a width of approximately 10 millimeters. This form factor is widely used in low-intensity automotive lighting roles such as cornering, parking, and side marker positions.
The W2.1x9.5d base type is standardized under international bulb nomenclature, where "W" denotes a wedge base, "2.1" refers to the contact width in millimeters, and "9.5d" describes the base body dimensions. Bulbs sharing this base type are physically interchangeable at the socket level, though wattage and voltage ratings must still match the circuit requirements.
