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, operates at 12 volts, and draws 5 watts.
The T10 wedge base design means the bulb is held in place by friction rather than a locking mechanism, allowing it to be removed by pulling it straight out of its socket without twisting.
The Hyundai Santa Fe uses the 12961 bulb for the stepwell position across the 2003 and 2005 model years.
At 5 watts, the 12961 is a low-draw bulb, which is typical for interior courtesy lighting positions such as stepwells, where the lamp is intended for brief illumination during entry and exit.
The W2.1x9.5d base designation is an IEC standard identifier, where W2.1 refers to the width of the wedge contact and 9.5d refers to the base depth, ensuring a specific physical fit within the socket.
Because the 12961 is a Philips-assigned part number, equivalent bulbs from other manufacturers sharing the T10 form factor and W2.1x9.5d base may be cross-compatible, provided the 12V and 5W ratings are matched.
