Additional Notes

The BMW Motorcycle C650GT uses the 12961 bulb across all listed model years, spanning 2013-2020, for the license plate position.
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 operates on a 12-volt electrical system at a 5-watt power rating, which is standard for low-draw auxiliary lighting positions such as license plate illumination.
The base type is W2.1x9.5d, a wedge-style base that relies on tension from the socket rather than a locking mechanism to hold the bulb in place.
The W2.1x9.5d base designation is specific and not universally interchangeable with other wedge base variants, as differences in pin spacing or body width can prevent proper fitment.
