Interior light lense

Does anyone manufacture the B pillar interior light lenses for the Series 2?
Or does anyone know of a substitute lense?
Cheers

No, that’s going to be one of those things you’ll need to either repair/restore, or keep your eyes out for or inuire about from a parts car.

As you are in AU, you may have some unusual options.
I’d suggest contacting everyday xjs and others like xks unlimited, welsh, etc as thry often have used parts and sources not listed.

Do the same in your area, make point to seek out parts cars and ask.

I believe it’s similar to the S1, no?

Found a pair listed on e b a y for $84USD…crazy.

If you have the originals and they are cracked or a hole has burned through due to passage of time, i would research various epoxies and consider restoring using some “creative” methods.

I feel your pain on those. They become so brittle in time…
Those are one of those very tricky items to get hold of, and worth buying extras if you come across just in case…

May also be worth searching e b a y for a generic or unrelated model, might get lucky modding, heating, bending, cutting a bit…etc.
That is if you have original trim piece.

Anyway, it’s that sort of thing with these hard to find items.
Good luck

Yes, same as S1. If yours are serviceable, I’d suggest replacing them with LED festoons in order to eliminate further heat damage. Easy to find, but some of the cheap ones have that annoying bluish spectrum.

Someone should do a rerun of these lenses. Can’t they be cast in resin easily? I‘d try mine but would have to look at them first as they don’t „clip“ in very well anymore.
+1 on the better led festoons.

I’m in AUS too. Did you every have any luck finding substitute lights for the B Pillar?

The part numbers for the Series III B pillar “roof lamps” are JLM554 and JLM555. They show up on eBay from time to time but they are rare and expensive, especially if new or in good condition.

Thanks for that Paul. Have seen them on ebay… very pricey. My car isn’t standard so I’m not wedded to originality. Think I’ll look to fit some alternative.

Cheers

I did buy some for an S1 from either Ebay or one of the usual suppliers (can’t recall), they weren’t cheap but there really wasn’t an alternative, it’s such an odd shape and the originals had embrittled with age and heat so just crumbled when I tried to restore them.

I would second the idea of going LED (even though I didn’t) because it’ll avoid heat build up and also if you leave a door open it’s much less power drain.

Bertiebloke,
A friend gave me a hand full off LED festoon bulbs and I have been evaluating them in various locations in our 1990 XJ-S convertible and Series III 1990 V12 Vanden Plas. In my opinion the light from the LED bulbs that I have is too harsh for use in the cabin where I installed them in the map lamps. They brightened up the trunk (boot) area much more than the incandescent bulbs do, so I may leave them there. I really liked how they brightened up the reverse lights in our XJ-S convertible and I will probably keep them there as well.
I don’t plan on using the LEDs for the B pillar roof lamps as that would be too harsh a look for me.

David, give Geoff at Jagara Spares in Sydney a call (he’s in Caringbah). I got mine, in excellent condition from Geoff. As others suggest a “warm white” festoon LED is the best lamp. Paul.

It’s all about getting the temperature right with LEDs. I’ve got some warm white bins, like 4500k, in the opera lights and they have the same tint as a regular buld.

I have a dim recollection of a process to heat and vacum form plastic. A simple version might work in DIY setting. Make senses in the shop!!!

Warm white is around 2700-3000K, but I’d guess that only halogen headlight bulbs come close to that. Old-fashioned 12V bulbs such as used in interior lights are rather “mellow yellow” than warm white. So, if you want to mimick the original looks with LEDs you probably need to go down to around 2000K.

In fact, for parts like these it might prove more helpful to dig into 3D printing as the parts are small, light and have a comparatively simple shape. The waffle pattern responsible for the opera light effect over the headliner might be analysed and programmed. Only downside, the printer won’t be able to create the chrome looks along the lower edge.

Good luck

Dumb question: Has anyone looked into 3D printing as the first step in investment casting? Like, 3D print something in plastic, use it to form a plaster cast, melt the plastic out, pour in molten metal?

I’m also wondering if anyone knows how to make glass items. I’ve watched glass blowing, but I presume there’s also casting processes for glass? If so, perhaps these interior light lenses could be reproduced in glass rather than plastic.

I bought a few LED festoons for this application and they were the very bluish type described in this thread. You get the most light that way, as the LED itself is blue, and phosphors add red and green to make white. As LEDs have become brighter (more efficient) folks are using better phosphors to provide warmer colour temperatures. I think festoons are behind in this evolution because of their relative oddity.

Anyone found a festoon suitable for the B-pillar light that’s suitable in colour temperature? I just polished up my lenses as much as possible–still not great, but I don’t want to reuse the hot tungsten bulbs.

It’s a valid point about the warmth of the original bulb colour. One of my favourite views of the red interior is night-time when the door opens and the map reading light is on, it’s a wonderful warm yellowish glow on the red leather, wood and chrome. Redolent (I like to think) of a 1970’s house of ill repute or Gentlemans club (some would say much the same thing).

Jochen,

I have had three different versions of the roof lamp lenses including ones with black, chrome, and doeskin bezels at the bottom.

You can ‘cast’ glass using a mould, that’s how most glass objects are made, but you would need a mould exactly as you would when you cast metal. I think that the correct terminology is ‘pressed glass’ but I may be wrong. You would need to make the mould out of a material that could take pretty high temperatures which may be an issue?

I know someone who makes moulded glass bowls etc. It’s a quite simple prosses, I don’t know how the press moulding works, but must be somewhat similar.

If there is a more general interest I could contact him and see if it’s feasible and what would be the cost.
I wonder how the clipping action would work though.
I also know someone who could make the aluminium mould.

My bad, you are correct. The ones I installed in the opera lights are 2700. I mixed up the specs with the cool white one I put in the opticell.
