The Jaguar XFR-S front outer turn signal uses a 3157NA bulb size while the rear turn signal requires a 12275 bulb size. The replacement chart covers 2013 to 2015 model years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Jaguar XFR-S uses two distinct bulb types across its turn signal positions: the 3157NA for the front outer turn signal and the 12275 for the rear turn signal, across the 2013-2015 model years.
The 3157NA is an ANSI-standardized bulb, meaning it conforms to a widely adopted North American specification used across many vehicle makes, which generally supports broad retail availability.
As a dual-filament bulb, the 3157NA operates two separate circuits within a single housing, typically serving both a lower-wattage running light function at 7W and a higher-wattage signal function at 27W.
The 3157NA carries natural amber glass, which produces an amber-colored output without relying on a colored lens or coating on the vehicle fixture itself.
The T25 wedge base of the 3157NA is a specific physical form factor; substituting a bulb with a different base type would result in an incompatible fit regardless of voltage or wattage ratings.
The 3157NA operates at 12V, consistent with standard automotive electrical systems, and its dual-wattage rating of 27W/7W corresponds to its high and low filament states respectively.
The 12275 is a Philips part number designation rather than an ANSI industry-standard code, which means cross-referencing to equivalent bulbs from other manufacturers requires verification against Philips-specific compatibility data.
The 12275 is classified as a specialty application halogen bulb, indicating it is not a general-purpose replacement type and may not be directly interchangeable with common bulb families without confirming socket and fitment compatibility.
The 12275 is rated at 12V, but its wattage is not specified in the provided data, which limits direct electrical comparison with the front outer turn signal bulb.
Because the front and rear turn signal positions on the Jaguar XFR-S use entirely different bulb types, the two positions are not interchangeable with each other.
