Additional Notes

The Audi A5 uses the 12961 bulb for the map light across the 2010-2014 model years.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor.
T10 refers to the bulb's tubular shape, with the number indicating a width of 10 millimeters.
The 12961 uses a W2.1x9.5d base, which is the standard wedge-type base common to many low-wattage automotive interior bulbs.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
At 5 watts, the 12961 is a low-power bulb suited to interior courtesy and reading light applications.
The T10 wedge format is widely used across automotive interior lighting, meaning the 12961 shares physical compatibility with many other vehicles using the same base type.
Despite broad physical interchangeability among T10 wedge bulbs, voltage and wattage ratings must match the socket's specifications to avoid electrical faults or premature failure.
