Additional Notes

The BMW 750Li uses the 12961 bulb for its license plate lighting across the 2006-2008 model years.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, operating at 12 volts and rated at 5 watts.
The T10 designation refers to a tubular bulb with a 10mm body width, a common format in low-wattage automotive auxiliary lighting positions.
The W2.1x9.5d base type is a wedge-style connector, meaning the bulb is held in place by tension from the socket rather than by a bayonet or screw mechanism.
The W2.1x9.5d base specification is a precise fitment standard; substituting a bulb with a different base type would result in an incompatible fit regardless of matching voltage or wattage ratings.
At 5 watts, the 12961 operates within the low-power range typical of license plate and courtesy lighting, where heat output and current draw are minimal considerations relative to higher-wattage bulb positions.
