The Jaguar XKR-S high beam and low beam headlight bulbs both utilize the D3S size. The replacement chart covers vehicle production spanning 2012 to 2015.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
ECE standard (Europe & worldwide). Mercury-free HID (xenon) discharge bulb with PK32d-5 base and integral ignitor, for projector-type housings. 42V, 35W.
The D3S is the sole bulb type specified for the Jaguar XKR-S across all listed model years and positions, serving both the high beam and low beam headlight functions from 2012-2015.
The D3S is a High-Intensity Discharge (HID) xenon bulb, meaning it produces light by creating an electrical arc through xenon gas rather than heating a filament, which is the operating principle behind its classification as a discharge bulb.
The D3S operates at 42 volts and 35 watts, which are standard ratings for automotive HID systems and reflect the high-voltage ignition requirement typical of xenon discharge technology.
The D3S carries the ECE standard designation, indicating it meets European and international regulatory requirements for road use, as opposed to SAE-standard bulbs designed primarily for the North American market.
The D3S features a PK32d-5 base with an integral ignitor, meaning the ignitor component is built directly into the bulb housing rather than existing as a separate part within the headlight assembly.
The D3S is specifically designed for projector-type headlight housings, making it incompatible with reflector-type housings without modification, as the optical design of each housing type is matched to a particular light source geometry.
The D3S is a mercury-free formulation, distinguishing it from earlier HID types such as the D2S, which contained mercury and are subject to disposal regulations in many jurisdictions.
Because the D3S incorporates an integral ignitor, it is not interchangeable with D4S bulbs, which share the same mercury-free and projector-housing characteristics but use a different base configuration and lack the built-in ignitor.
