Additional Notes

The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, operating at 12 volts with a 5-watt output.
The T10 bulb uses a W2.1x9.5d base, a wedge-style base type that relies on tension from the socket rather than a locking pin or bayonet mechanism to maintain contact.
The BMW X1 uses the 12961 bulb for the map light across the 2012-2015 and 2021-2022 model years.
Because the W2.1x9.5d base is a standardized wedge format, the 12961 is physically interchangeable with other T10 wedge bulbs sharing the same base type, provided voltage and wattage ratings are compatible with the vehicle's circuit.
At 5 watts, the 12961 falls within the low-wattage range typical of interior courtesy and reading lamp applications, where heat output and current draw are kept minimal.
