Jaguar S-Type headlight bulbs utilize 9005 and H1 sizes for high beam applications and H7 size for low beam, with each bulb size corresponding to specific lighting functions. Replacement chart data covers 2000 through 2008 model years with bulb size specifications for headlight configurations.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Jaguar S-Type uses three distinct bulb types across its headlight system: the 9005, H1, and H7. All three are single-filament halogen bulbs operating at 12 volts, though they differ in wattage and base type.
The 9005 bulb follows the ANSI standard used in the United States and Canada. It draws 65 watts and uses a P20d base, making it the highest-wattage bulb among the three types specified for this vehicle.
The H1 and H7 bulbs both follow the ECE standard, which governs lighting equipment across Europe and much of the world. Both operate at 55 watts and carry approval for use in the United States and Japan as well.
The H1 uses a P14.5s base, while the H7 uses a PX26d base. These base types are physically incompatible with one another and with the P20d base of the 9005, meaning the three bulb types are not interchangeable.
The H7 bulb serves as the low beam headlight across all model years of the Jaguar S-Type covered in these specifications, spanning 2000-2008 without variation.
For the high beam headlight on 2003-2008 S-Type models equipped with Halogen Capsule Headlamps, the specified bulb is the 9005. Those same years equipped with HID Headlamps use the H1 instead, reflecting a difference in headlamp system design rather than a simple bulb substitution.
The 2000-2002 S-Type high beam headlight specifications list only the 9005, with no HID headlamp variant noted for those years.
Because the high beam application for 2003-2008 splits between the 9005 and H1 depending on headlamp type, the installed headlamp system on a given vehicle determines which bulb applies, and substituting one for the other would not be compatible due to differing base designs and wattage ratings.
