The Jaguar Super V8 side marker utilizes a 12961 bulb size for illumination across all recorded vehicle applications within the provided technical data set. Available information covers the specific range from 2005 through 2009 for the identified component.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Jaguar Super V8 uses the 12961 bulb for both front and rear side markers across the 2005-2009 model years.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor.
T10 refers to a tubular bulb with a width of 10 thirty-seconds of an inch, a common sizing convention in miniature automotive lighting.
The 12961 bulb operates at 12 volts and draws 5 watts, placing it in the low-wattage category typical of side marker applications.
The W2.1x9.5d base type is a wedge-style connector, meaning the bulb is held in its socket by the tension of the base itself rather than by a separate locking mechanism.
The W2.1x9.5d designation specifies the contact width and insertion depth of the wedge base, which governs physical socket compatibility.
Because the same bulb size is specified for both the front and rear side marker positions on the Super V8, a single bulb type serves all four side marker sockets on the vehicle.
The T10 wedge format is widely produced by multiple manufacturers, though the 12961 designation is specific to Philips and may not correspond directly to equivalent part numbers from other brands.
