The Jaguar XJR fog light requires a 9006 bulb size for the front lighting assembly. Data for the specified component covers the range from 1998 through 2003.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Jaguar XJR front fog light draws from three distinct bulb types across its model years: H3, 9006, and H11, with H3 appearing most frequently across the listed range.
The H3 is an ECE-standard single-filament halogen bulb rated at 12V and 55W, fitted with a PK22s base. Its approval extends across Europe, worldwide markets, the US, and Japan.
The 9006 is an ANSI-standard single-filament halogen bulb rated at 12V and 55W, fitted with a P22d base. Its standard originates in the US and Canada.
Although the H3 and 9006 share identical voltage and wattage ratings of 12V and 55W, their base types differ, with the H3 using a PK22s base and the 9006 using a P22d base, making the two types physically non-interchangeable.
The Jaguar XJR (2004-2008) front fog light takes an H3 bulb, while the 2009 model year shifted to the H11, which uses a PGJ19-2 base and is likewise rated at 12V and 55W.
The H11 carries ECE certification and is also approved for use in the US, placing it in the same broad regulatory acceptance as the H3, though the two bulbs are not interchangeable due to differing base designs.
Front fog light fitment for the 1998-2003 model years uses the 9006 bulb, while the 1995-1997 model years return to the H3, reflecting two separate bulb type transitions within the front fog light position across the full XJR range.
The P21W is an ECE-standard single-filament signalling bulb rated at 12V and 21W, fitted with a BA15s bayonet base. At 21W, it operates at a notably lower wattage than the halogen fog light bulbs used elsewhere on the vehicle.
The rear fog light position on the Jaguar XJR uses the P21W bulb for the 1995-1997 model years, with the BA15s bayonet base being a widely used fitment in European-market signalling applications.
The P21W's bayonet-style BA15s base is mechanically distinct from the pin and wedge bases found on the front fog light bulbs, meaning no cross-fitment is possible between the rear fog light bulb and any of the front fog light types listed in the specifications.
