2006 XJ8L. The manual in the glove compartment gives instructions for replacing the outside headlight bulb but warns that there are two types halogen and xenon. With much difficulty due to lack of clearance, I got the chamber opened but cannot extract the bulb. Then I noticed that it looks very different from the halogen replacement bulb I purchased. =left Can anyone confirm if this is one of the xenon bulbs, and if so, can I get detailed instructions for replacement? There is no dealer within 300 miles, and no one in town will work on Jaguars. =left

The xenon (HID) require ballasts (one for each light) to create the electric arc. I would assume that in the absence of the ballasts the bulb needed is a halogen.
If what appears to be a box on the end of the glass capsule reallyis a rectangular box (in the RHS of the picture) then it's an HID lamp, not a halogen.
The box is indeed rectangular, but the diagram in the manual shows a rectangular box for the halogen bulbs also.
My major issue is how to get access to the bulbs. There is little clearance behind the light assembly and no way I can see to remove it without removing the front bumper. I was only able to open it as far as I did by bending a support and disconnecting two sets of wires. Still wasn't enough to extract the bulb, let alone replace it.
Hi Mark,
Looking at the photo you posted it does appear to be a Xenon bulb - they all have a brown bar that runs parallel to the glass section. Jaguar began introducing Xenon headlamps as options across the model range around 2000/1. The problem is that the extra space needed to install them, the HID ballast pack and igniter make them impossible to replace without removing the complete headlamp - not enough room between the rear of the headlight and the front sub-frame.
To change these out you will need to remove the front bumper, front splash guard and perhaps also the inner front wheel splash guards - it can be a bitch of a job if the speed fasteners securing the splash guards are heavily rusted.
I had to do this recently on my S Type to fix a droopy headlight problem so have some recent and unhappy experience.

Replacing the headlights is a big job. I just did mine this weekend (took about an hour and a half) but on my car the large pan underneath the engine and the front splash guard were already off the car. You need to remove the grill (easy), splash guard and bumper cover. Then remove the three headlight bezel screws, wiring harness and wiggle the bezel out of the car. I lowered only one side of the bumper cover at a time making re-assembly much easier. I suggest replacing the bulb with the whole unit on a work bench. None of this is particularly difficult but a bit much just to change a bulb. As others have said, It's much easier the second time around. And remember, don't touch the new bulb with your bare hands. Oil on your skin will shorten the life of the new bulb. Seriously, you can do it!
Replacing the HID bulbs is easy as pie. Bumper stay on, so does the grille, the headlight stays in the car, too. Here is my write-up, I've just done it a few weeks ago, took maybe ten minutes per side.

Good to know that there is an easier way for the XJ, clearly theres sufficient clearance between the sub-frame and rear of the headlight unit. Sadly, your method will not work for the S Type, only about an inch/2cm clearance so no way to get the HID Igniter and bulb out. More importantly replacing the power supply wire to the igniter, which pops out of its socket automatically when the igniter is released from the bulb, would be impossible. That said I'll keep a note of your thread for referral to other XJ drivers.

It works brilliantly this way with the XJ. I haven't a clue about anything S-Type. It's unfortunate a similar simplification of procedure doesn't work for the S as it's a proper time and labour saver on the XJ.
