Additional Notes

The Mercedes-Benz C300 glove box uses the 12961 bulb across the 2008-2023 model years, indicating a single fitment specification for this position throughout the entire production range covered by these specifications.
The 12961 is a Philips part number designating a T10 miniature wedge bulb, a format widely used in low-intensity interior lighting positions such as glove boxes, map lights, and courtesy lamps.
The bulb operates at 12 volts and draws 5 watts, which is characteristic of a low-power incandescent interior lamp intended for brief, intermittent use rather than sustained illumination.
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, and it is removed by pulling straight out.
The T10 designation refers to the bulb's tubular envelope width of 10 thirty-seconds of an inch (approximately 3.175 mm), a standard sizing classification used across many automotive interior applications.
Because the W2.1x9.5d wedge base is a widely standardized format, aftermarket and LED replacement bulbs marketed as T10 or 194-type are frequently listed as compatible, though electrical compatibility with the vehicle's canbus system is a separate consideration not addressed in these specifications.
