Condensation in headlights

Hello all,


One of the many issue areas on my Silver Spirit II (92) is the amount of condensation it gets in its headlights after use. Well, not always just after use actually.


When I bought it and pointed out to the dealer there was a LOT of mould in the headlamps, he said I would be able to take the glass out and give it a wipe around on the inside.


I've since found out this is not the case and I suppose there's a leaky seal. It's on both sides of the car. Shame really, it looks so unsightly, but I guess there is no simple solution? Presumably new headlights at an extortionate £price?


Regards
James.

Call the dealer, make an official letter reminding you pointed this point.
Try to find a solution with him.
You need to be very persuasive and responsaibilise him.

Have you a dealer warranty ?

Hi James,


If it is bad and damaged/degraded the reflective surface it is usually an MOT failure point.


At the very least it should have been recorded as an observation.


Trouble is with dealers they usually can get things through as MOT station likely gets a lot of business from them.


So yes likely new lights required.


All the best


Steve

The glass lens is held on by clips which often break. The is a rubber rope that fits into a groove for a seal. The entire headlamp assembly must be removed.

Here is an illustrated view with part numbers.

Most likely the rubber seal is breached leading to moisture ingress. You could add silicone to the mix or get a new seal. You may need new clips to hold the lens onto the housing.

I would suggest doing the surgery over a carpet in case things "get out of hand"

I would also have to imagine that these headlamp assemblies, much like the ones on my 1989 Deville, have drains/vents in the form of very slim tubes somewhere. These can become blocked and not allow moisture egress as well.


One of my headlamps on the Cadillac had a small chip in the lens with a pinhole allowing moisture in, which is also something to check carefully for, though from the photograph this does not seem to be the case with yours.

Unfortunately, I've already had a full and final settlement with him when I complained about a number of other things.

Thanks Steve, I think one day I will get new lights, because they do spoil the look. I dare not think how much they would cost!


Yes, I mentioned my issues with the dealer on his choice of MOT station. After a Rolls specialist did an assessment on the car, he said some of the advisories were a nonsense, ie not true. And things that should have been FAILURES, were not included.


But this raises an interesting question. Should you take a complicated car like an elderly Rolls, to any old MOT station? That in all likelihood, has never been near one ever before? Or is it best to go to your Rolls Royce specialist and get them to take it to an MOT station which they have used themselves? So there's an outside chance the MOT assessor does actually know the cars....

Thanks Wraithman for that weblink, very interesting. Something that seems so simple, but when you look into it, really actually isn't that simple...

That's a good point Brian. Whilst I'm pretty sure there's no chip in either of the lens, I will just go double check. The car has not been loved for a good decade, so nothing surprises me now...
