Land Rover Range Rover Sport Side Marker Bulb Size
The Land Rover Range Rover Sport side marker utilizes a 12961 bulb size for illumination purposes. Data for the specific component covers the range from 2010 through 2013.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Land Rover Range Rover Sport (2006-2009) uses the 12961 bulb for both front and rear side markers.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor with a W2.1x9.5d base.
The W2.1x9.5d base is a wedge-type base where the bulb is held in its socket by the tension of the base itself rather than by a bayonet or screw mechanism.
The T10 designation refers to the tubular glass envelope of the bulb, which is 10 millimeters wide.
The 12961 operates at 12 volts and 5 watts, placing it in the low-wattage category typical of parking and marker lighting applications.
The front and rear side marker positions share the same bulb specification across all four model years covered, indicating a uniform fitment throughout the generation.
The W2.1x9.5d base type is a standardized international base designation, meaning equivalent bulbs from other manufacturers sharing this base and the same 12V/5W rating are generally interchangeable with the 12961.
