Looks at the photo for any D3S bulb, like this...

That one has a blue insulator. If that’s damaged, I would think it may arc to the glass body if there’s any surface contamination.

The OP was talking about part of the globe itself!

It was the return wire I damaged so I bit the bullet and replaced it (errrrrr). BTW.... I found changing the lights much more difficult than most indicated on the forum. Access on of both sides my 2015 V8S was a bear even after moving the fuse box and reservoir out of the way. My fuse box wires were secured to the body below the box limiting how far I could move it. Disconnecting the plugs from the bulbs themselves was also way harder than it should have been (although I saw someone else had an issue with that too). And lastly, locking down the lights back into place was the worst. Perhaps the size of my hands was an issue along with the limited space, but I really struggled to manage this while not damaging the bulb (or the return wire in this case). Technically not very complicated of course, but one of the "easy" projects that ends up taking you far longer than you ever expected.

I read somewhere here that it's fairly easy to loosen off the front bumper one side at a time, without dropping it completely and without removing all that many bolts, and then you can gently pull that side of the bumper away just enough to get at the third/underneath headlight mounting bolt (the top two are easy to get at anyway) and then you can completely remove the headlight assembly which would make replacing the globe so much easier.
I know at the time I commented that next time I replace a headlight globe I will try that method.
I'm too lazy to search for that post though so I'll leave it up to someone else!

I gave it a go over the weekend and it worked. There is a switch to release the bulb. Once you know how, it is an easy 15mins DIY exercise. For the ones being no semi-professional mechanics, here is a brief step-by-step guide on how to replace the D3S xenon bulb in the passenger headlight of a MY14 (I have pre-facelift bi-xenon headlights with this moving-with-the-steering-option):
- Open the bonnet, make sure lights are switched off.
- Passenger side: the headlight has a rubber cover on its back. The bulb is behind it. Its access is blocked by a black/red fusebox.
- Undo two bolts that are holding the box.
- Plug out the black connector out of the socket of the very external side of the headlight (to release the black cable being between the fusebox and the headlight). Careful - you need to press a plastic piece to release it, no force required.
- Once both bolts are gone and the connector is unplugged, you can move the fusebox up towards the radiator. This way you should gain comfortable access to the rubber cover of the headlight.
- Open the rubber cover, you will see the back of the bulb. The bulb is connected via a cable on its lower end.
- On the left side of the bulb, you will see a small black plastic - it is a switch, move it. This should release the bulb.
- Pull on the bulb to loosen it. Once loose, unplug the connector of the bulb. It is the most inconvenient part, careful not to brake it.
- Once unplugged, you can take out the old bulb and replace it with the new one. Follow the steps above upwards to connect and close everything.
- Pull on the bulb to loosen it. Once loose, unplug the connector of the bulb. It is the most inconvenient part, careful not to brake it.
I got to this point (pulling the electrical connection off the bulb) and could not get it off....was afraid of breaking it. Is there a catch/trick to doing this....
Thanks all!

I am assuming you have already turned the locking ring to release the bulb? And you are talking about pulling the BULB out. The plug has a clip to press and then it pulls out too, but very tight!
Good luck

Thank you. That is exactly what I needed to know. (both of the last two replies have been awesome, thank you!!!)

Yes that wire to the DS3 bulb is a pain and I also had to lever it off like OzXFR. Even then I never could see what tab needed to be depressed. I distorted the sheet metal shell a bit but was able to reform it back close to factory using pliers. This was NOT on a Jaguar as I have LED headlights in my XJR.
I used some upgraded bulbs but they are expensive at around $250 for the pair.
I used Phillips 42403 XV2 Xtreme Vision bulbs. Anyone use these? Just installed them so claims of better light output are hard to determine.
I replace them in pairs as the bulbs degrade over time and the car was a 2013 model (Lincoln MKS EcoBoost) so a good number of years on them. I first noticed the reduced HID light output on my old 2005 S-Type R. Replaced one side at first and noticed it looked different from the original side so then replaced that side too so they looked the same.
