Additional Notes

The 12961 is a Philips part number designating a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12 volts and 5 watts.
The W2.1x9.5d base is a wedge-type connection, meaning the bulb is held in place by tension from the socket rather than by a bayonet or screw mechanism.
The Hyundai Elantra N uses the 12961 bulb for its side markers across the 2023-2024 model years.
The T10 designation refers to the bulb's tubular form factor, with a width of 10 thirty-seconds of an inch, a sizing convention common in miniature automotive lighting applications.
At 5 watts, the 12961 operates at a low power draw consistent with its role as a marker lamp rather than a primary illumination source.
