The Mercedes-Benz S65 AMG parking light requires a 12961 bulb size for proper installation and function within the lighting assembly. Data for the specific component covers the period from 2006 through 2013.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mercedes-Benz S65 AMG uses the 12961 bulb across all listed model years for its front parking light position, spanning 2006-2013.
The 12961 is a Philips part number designating a miniature wedge bulb of the T10 type, operating at 12 volts and rated at 5 watts.
The T10 designation refers to the bulb's tubular form factor, a widely used classification in automotive lighting for small-capacity bulbs.
The W2.1x9.5d base is a wedge-style base, meaning the bulb is held in its socket by the tension of the glass envelope itself rather than by a separate metal cap or locking mechanism.
At 5 watts, the 12961 is a low-power bulb consistent with parking and position light applications, which are not required to produce the output levels associated with headlamps or fog lights.
The 2006 model year carries an additional notation identifying the front parking light position as a clearance light, distinguishing its functional classification from the unlabeled entries of later years.
Because the same bulb number appears across all listed years without variation, the front parking light socket specification remained unchanged throughout the 2006-2013 production span covered by these records.
The W2.1x9.5d base standard is defined by the IEC, and bulbs sharing this base type are physically interchangeable at the socket level, though wattage and voltage ratings must still match the vehicle's circuit requirements.
