One Headlamp or Two? Jaguar XJS V12
I had a huge problem when I uprated the quads on the Scabby Cabby and gave up in the end; I think that the higher output bulbs had blown some inline fuse somewhere that I couldn't locate.
I think that the trick is to put extra relays in to handle the higher current draw (could be completely wrong of course!).
The biggest pain will be removing the old main mounting brackets and fitting the new ones as access is a little tight.
You have to get the mounts first of course.
Which I just happen to have...............

if you are basing your theory that both lights where original because of this photo :
then you are incorrect. Jaguar had already had to compromise the original covered lights on the E type due to the U.S. market regulations across the entire E type range , so on the XJS they made The original lights for England and the rest of the world and US only lights for the U.S. only.. this is the reason that "quad" lights are only found in the US and absolutely no-where else (when new)

OB,
You certainly know how to get conflicting opinions from the members here! I'm so looking forward to your next 2 threads - "Should I put chrome wheelarch lips on my XJS?" & "I'm thinking of fitting an economical diesel engine in my V12 convertible"!!
Just to add my fuel to this fire:
It seems pretty clear that Jaguar designed the XJS to have ovoid headlamps but recognised early on that the vagaries of US legislation meant that they had to fit a compromised twin light setup for that market. I think that's reinforced by the fact that as soon as legislation had changed by the time of the facelift, they immediately fitted the ovoid headlamps to the US market as well. The US facelift ovoids are not just LHD lights, they have perspex lenses instead of the glass ones that are fitted in other countries. I think even Germany has glass LHD lenses on their XJS lights. I find it interesting that ovoid lights seem to be referred to as "Euro" lights whereas they are really the "worldwide" headlights and twin lights are "early US" fitment.
I suspect that the majority of views are influenced by how people first remember seeing an XJS. US owners first saw an XJS with twin headlights whereas everyone else saw XJSs with ovoid headlamps and slim bumpers, and thought twin headlamps and ugly big bumpers were a US legislative compromise.
The fitment of twin lights in the UK to XJSs only really happened from 2004 when the facelift lights became unavailable new. There were even reports of cars being scrapped because they couldn't replace a broken light and pass an MoT. This gave rise to the much increased prices of good 2nd-hand units. I bought one of the last new lights and a 2nd-hand one at the time as contingency for the day when I break a light. (I also fitted the rare Jaguar perspex light over-covers as protection).
There's no doubt that twin lights give better light output than the poor ovoid light output. However, that can partially be remedied with the significant improvement from the fitment of bulbs such as Philips X-treme.
If I was building a track car or a modified custom XJS, I might fit twin lights. However, for standard cars, I would always go with the original fitment. But then I just like the original look. If I lived in the US and had an early XJS, I'd probably like twin headlights!
Greg's comment about me having a pair of new late facelift US ovoid lamps has actually made me feel guilty about keeping them! They may be worth big money, Greg, but not quite the pension plan that you suggest! I originally bought them "just because I could" and thought that one day I would sell them to a concours participant. But I think I might just sell them now to a worthy owner. (Watch out for a 'For Sale' thread soon!)
So, my suggestion, OB, is stick with the originals because you know deep down that it's one of the reasons you love the car! But definitely upgrade the bulbs with Philips X-treme or similar.

My personal preference is for the quad lights. To my eye it looks better than the euro lights.
I also prefer the look of the pre-face lift cars. On the face lift cars I think the euro lights look appropriate.

I liked the quad lights as I ran aircraft style lights for high beams. I upgraded the low beams to a better bulb and wiring and rewired for high heat in the high beam aircraft lights. Fog lights under bumper with headlights were good at highway speeds at night, but the aircraft high beams could see for a mile while at speed. The single light looks good, but for function quads are better. The Europeans were converting the single lamp style to quads for more light. If you are going for your own style, go with what you like. If you want function, go quads.

The 'Chrome Wheel Arches' look hideous and whenever I see them on a Car, I always think that they were put on to hide 'RUST'
As for fitting a Diesel, now that's a different matter altogether, as I really do like the idea of fitting a Diesel but only on the proviso that it could be an Automatic.
Having said that it would probably kill the Performance, which is really what its all about.
But then again in an ideal World, I would have a Diesel XJS as a Daily Driver and a V12 XJS or the Summer.
P.S.
I nearly fell off the Wagon to-day, when I came across one of the New Shape XJ6 to use as a Daily Driver, it was absolutely gorgeous and would have loved to have it on my driveway.
Just for the 'Pose Factor' alone! but somehow I just managed to resist, though had it been an XJS to add to my little Collection, then I'm sure it would have been a done deal.

I have no leaper, and I have also changed my lights to the quad set-up, personally I like the look so much better then the singles, they tend to look like a frog from the front IMO. I kept my old lights, you never know one of children may take interest in it and change it back. Its simply personal preference, and I was never big on square singles, I think its just what dad had bought that was the big influence, started with a 64 Toyota Dyna truck and then a Ford ZB Fairlane then a Holden HQ Statesmen, all had quad round headlights.
Must be just genetic programming I think.

Before I had an XJS I thought the singles looked odd, because I hadn't seen them much. The car I own has single euro lights on it and the more I see double american lights the more I hate them. Everytime I see them IRL they just look so cheap and thrown together. They don't look like they belong on the car at all.
I suspect the only reason many other people like them is because it is what they are used to and they like the XJS regardless, so never put much thought into the dual headlights until they eventually saw singles and it looked "wrong" to them.
I think the doubles are pretty hideous and have a detrimental effect on on the elegance and look of quality to the car.
Not meaning to be offensive to anyone or say their cars are ugly. I just think they look ridiculous.
EDIT: I wrote singles instead of doubles in one spot

Its a very tricky dilemma, as I have never actually seen an XJS with Quads in the flesh, so I think I need to do so, before I make up my mind.

I quite like the Quads on the 'Gothic' pre face lift design but as I don't have any 'at the moment' then I will probably stay with the Single Light set up.

At least two XJS's are the bare minimum.

coupe? I could see them on a old english white convertible with a blue top, maybe because the top has a business to it that follows the quad lights and something about the white fixes the cheesy plasticy look to the headlamp surrounds a little. BUT i think it would still look better with singles

I think they both have merits, I'm neither drawn to or away from either. I feel the quads look better on the pre facelift and the singles look at home on the color bumper facelifts. I'm not going to get into phyco babble on my brain being conditioned because I own quads and am used to them, therefore I know no better....now THAT is ridicules!

They don't look quite as bad as that on my Car, although I see what you mean.

right from the early prototype days of the design BOTH types of headlights have been on the XJS
there is a photo in one of the ' XJS ' books showing a half and half car with one euro and one quad fitted to it in the factory , as the quads were always designed for the US market ( and others ) from the beginning knowing the euro headlight would not pass regulation , this picture also shows early rear quarter designs and XJ trims on the car as they were trying things out
so, its down to taste and market and what you are used to
I personally think the Euro design is in keeping with the lines of the car, but I also think the quad setup gives the care more attitude
I have resisted fitting quads to my fully bodykitted XJS

Dunno, the look pretty cool on that Black XJS, I quite like them!
