The Jaguar XE uses D3S and H15 bulbs for high beam headlights, while low beam headlights require D3S and H7 bulbs in the specified size configurations. A replacement chart covering 2017 to 2019 model years documents the bulb specifications for this vehicle.
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 Jaguar XE (2017-2019) uses two distinct headlamp system types across its model years: HID (High-Intensity Discharge) and halogen capsule, with bulb selection depending entirely on which system is fitted to the vehicle.
The D3S is the HID bulb used in both high beam and low beam positions on XE trims equipped with HID headlamps. It operates at 42V and 35W, incorporates an integral ignitor, and is designed exclusively for projector-type housings with a PK32d-5 base.
The D3S is a mercury-free xenon discharge bulb, conforming to ECE standards applicable in Europe and worldwide. Its mercury-free construction distinguishes it from earlier HID generations such as the D2S.
On halogen-equipped XE models, the high beam position uses the H15 bulb, a dual-filament type with a PGJ23t-1 base rated at 12V and 55W/15W. The two filaments serve separate functions within a single bulb envelope.
The low beam position on halogen XE models uses the H7, a single-filament bulb with a PX26d base rated at 12V and 55W. Unlike the H15, the H7 holds approval not only under ECE standards but also in the United States and Japan.
The H15 and H7 are not interchangeable despite both being 12V halogen types. They differ in filament count, wattage configuration, and base type, making cross-substitution physically and electrically incompatible.
The D3S integral ignitor design means the bulb and ignitor are replaced as a single unit, unlike D2S systems where the ignitor is housed separately within the ballast assembly.
All three bulb types specified for the XE conform to ECE regulations, reflecting the vehicle's European engineering origin, though H7 additionally carries approval for North American and Japanese markets.
