Paul, I did the swap on my '92 to go to the quads. It's not that difficult, with the exception of reaching one of the torx bolts holding the headlight assembly to the frame. As far as the wiring, I did 'cheat' and buy the quad headlight kit from SNG barratt. The wiring on this kit a direct plug in to the existing wiring, so I didn't have to splice wires or anything. The quality of the SNG kit and the lights is very good imo.

To remove the old lights, release the 2 headlight adjustment cables that are secured to the inside of each inner fender. You can feed the cables through the fender and access the rear of each headlight via a panel in each front wheel well.

Remove the 3 screws from each chrome trip piece to remove those pieces from the headlight - one of them is on top, only accessible with bonnett up, and easier with a short screwdriver. Then there are 4-5 torx bolts (t30 I think) holding the headlight assembly to the frame. You'll need an extended length screwdriver with torx end to reach them. As I said, one of them on mine was very difficult to reach. On my car (LHD), it was the one at about 1 o'clock on the passenger side and 11 o'clock on the driver side (facing the headlight). Basically reverse the process with the quad lamps.

I tried attaching a few photos.

 

i did mine a little different, 16yrs ago, today if i were to do over ,id use HIDS.

outside is hiway driving lights, sealed beam.

inside lights projector beams,

 

Keith, if i could get some details on doing this, I would be MOST appreciative.... This is my first "newer" British car in many years.. the last being a 1977 MGB. I have some familiarity with Lucas Electronic's and their quirks, but I am not sure if while under the Ford regime if anything was changed in that respect.

I have a guy who has the sealed beam lamps from a 1991, and in trade he wants my Euro styled ones, which like you, I can't stand the look of. Any pictures/ notes/ hints and or tips on doing this, I would GREATLY appreciate..... I will post some before and after's too.... Would personal e-mail be better for this? If so I will send it your way via personal through here, and let you decide.

Thanks,

Donovan

 

Ha ha , I just swapped my 88 quads out for the euro glass lamps. Took me several tries to get two that matched well enough. It seems a big problem with these is the silver lining fades off especially top,and bottom in the back of housing. I actually used a piece of cloth on a metal rod and used chrome bumper spray to carefully re silver.
That alone greatly improved lite output. Then I changed bulbs to the newer sylvania hyper white bulbs and I can assure you the light is amazing! WAY better than my old quads.
I, personally, dislike the quads after hearing how much they remind friends of that movie Christine".
I have a set of quads with everything needed and I even have the cool led halo replacement bulbs as well. The led halo rings do need to be wired separately either to park lights or can be wired to stay on ad drl, ie BMW.
Let me know if anyone is interested.

 

pictures?

 

Hi All,
I must have a good set of original headlights as I have no issue with brightness, in fact I would go so far as to say that they are better than my wifes' 2005 A4.

 

Bit of an appearance difference in a '56 Plymouth Fury and a XJS I would say though..... Besides I liked Christine...

 

Yeah I know,I actually like the movie and book too. Think I'm just one of the few fans of the euro headlight. The quads simply remind me of 60's muscle cars and I think the euro lights just look right on it.
The xjs was never supposed to have quads but the USA market wouldn't allow the single units due to dot regulations.
Reminds me of my 2010 XF lights. Jaguar was worried the XF was too extreme for traditional buyers so they tried to keep that hooded round headlamp appearance giving a surprised cat eye look! But the face lift sorted out that issue with the original concept sleek headlamps.
Sometimes I think Jaguar doesn't trust their own instincts for change. Look at the xjs, longest running model in jaguar history and most provocative leap in design from previous models. (Of course they couldn't afford to introduce a new model either!)

 

Yeah, the quads look great on your car. Now you have me thinking about it, though I struggle with the originality issue.

 

Hi.
If you're interested, I have the complete quad headlight assembly from my 88. It has two sets of bulbs, the regular halogen sealed beams, and a set of led halo bulbs with changeable headlamp bulbs.

 

Well well well...that's awfully tempting, thank you. Do you have a figure in mind (direct message if you prefer)?

 

I would say anything pre-Ford though would be original. Post Ford, not so much so why not? 32 three window coupe's tend to have Chevy transplants in them, the 95 XJS has a Chevy transmission, owned by Ford so. ?

 

Actually, in 1990 jaguar offered a limited "Le Mans Celebration" edition only available in UK with the standard USA quad headlamps.

 

True, and the quad lights are still Jaguar parts. That's settled then.

 

Simple fix for the top hitting the back seat is to remove the back and "adjust" the seat frame panel with a hammer and a 2x4. It worked for me.

 

I need to change the headlight on my UK car for LHD/German traffic.
Is is possible to put pre-facelift headlights into a facelift car?

Thanks,
Peter.

 

I find it interesting that those who have UK headlights want to swap for quad and vice vertsa. Should start a thread for headlight exchange.

 

Peter,
easy route is to order the quad lights with LH dip and the wiring loom.

 

Yes, from what I've seen, any pre facelift quad lights will fit any facelift car. My 95 XJS has 88 lights. A direct fit, except the wire connectors. And according to one of the earlier post on this thread, you can buy a direct fit wiring harness to make the swap.

 

I have an '89 with euro headlights. I am assuming someone must have changed them in the past and I am thinking of returning to the quad classic look.

Anyone that has done this switch - was the light output significantly less with the quads than the euro? I see one post where the he said the euro seemed brighter, and another post where the quads were very bright even compared to a modern audi. Any first hand experience?

Second, if I'm doing this, I'll have euro style lights to get rid of. Anybody interested in a trade or purchase after my conversion?
