The Jaguar XFR front outer turn signal uses a 3157NA bulb size, the front turn signal requires a 3457NA bulb size, and the rear turn signal uses a 12275 bulb size. The replacement chart covers vehicle production years spanning 2010 to 2015.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Jaguar XFR uses three distinct bulb types across its turn signal positions: the 3157NA, the 3457NA, and the 12275.
Both the 3157NA and 3457NA are ANSI-standardized dual-filament wedge bulbs of the T25 form factor, rated at 12V with a 27W high filament and a 7W low filament, and both feature natural amber glass rather than a clear envelope with a colored lens.
Natural amber glass produces the amber signal color directly from the bulb itself, which satisfies regulations in markets where the lens alone cannot provide sufficient color filtering.
The 3157NA and 3457NA share the same voltage, wattage, and T25 form factor, but they are not interchangeable. The two types differ in their base contact configurations, meaning one will not seat or function correctly in a socket designed for the other.
The front outer turn signal position on the Jaguar XFR uses the 3157NA across all model years covered, spanning 2010-2015.
The front turn signal position, which is a separate position from the front outer turn signal, uses the 3457NA and is specified only for the 2010-2011 model years.
The rear turn signal on the Jaguar XFR uses the 12275 across all model years covered, spanning 2010-2015.
The 12275 is a Philips part number designation rather than an ANSI industry-standard code, indicating it is a specialty halogen bulb rated at 12V and sourced through Philips-specific supply channels.
Because the 12275 carries a proprietary part number, direct substitution with a generic or ANSI-coded equivalent requires verification of physical and electrical compatibility before fitment.
The split between front outer and front turn signal positions in the 2010-2011 model years indicates the XFR carried two physically separate front turn signal assemblies during that period, each requiring a different bulb type.
