Lunar internal light problem

Campbells might be a bit dim, but the black greasy handprints left at first service on our cream interior weren't. Never mind, a bit of rag and some brake cleaner did the job after we pointed them out!

As you can imagine, 2nd and subsequent services conducted elsewhere.

Update.......as suggested by the very helpful replies I  wiggled wires,fuses etc here and there and checked battery neg and pos connections etc. It's down to dodgy connections somewhere between the fitting itself and the wiring after it has disappeared out of reach. I unscrewed each of the downlights and when moving the fitting and wires around they sometimes work and sometimes don't. The connections at the fitting are all sealed and the wires disappear into holes in the paneling.The frustrating thing is I had one working and when I screwed it back in place it stopped again. Anyway all is now working and I will just see what happens. I assume if it keeps happening it should be covered under the warranty.Thanks again for all the help

I`ve had an LED Strip on the underside of a cupboard go dim and in my current van one of the corner cubes is not working correctly both Lunars. We soon changing so will let dealer sort out.

If the fault is due to poor connections i.e. workmanship and that is accepted the repair should fall within the warranty, the year applies to the bulb failure?

I have 7 years old lunar lexon 560  just bought and noticed the kitchen bulkhead led and one of the corner led's are not working. I find it astonishing that these are "not replacable", we all know by now that contrary to popular myth, led's do not by any means last forever. In fact I  have had led bulbs that did not last as long as conventional bulbs, given where they are manufactured this should be no surprise. 

I will check out the connections etc but I suspect that 7 years is a reasonable design life for any electronic component. On my car I have had indicator   led's  that have gone within 4 years.

I have sourced come similar led units on line although I am not sure yet how these would be fixed as the originals appear to be hard wired in. I am  some what  aggreived  given that this appears to be such  a common problem that a quick fix is not available to caravan owners. Obviously this will be an ongoing problem for older caravans and it would appear that no one has bothered to come up with an easy and cheap solution. Even the dealer I bought the caravan from could not offer any help.

Someone please tell me I am wrong.
