LED interior lights not all working

[Chazbaglan83]

Two of my four VW T6 interior lights have stopped working all of a sudden. Any advice on how I could try and fix them would be very helpful, please?

I don’t have a leisure battery so assume they are powered by van battery. Pics attached show the lights and switch I have, and it’s the two closest to the tailgate which have stopped coming on. Happy Sunday, and thanks for any advice!

Did they all work before?

For how long?

If so id assume a poor conction at some point.

You might need to pull the trim and follow the wires to the lamps looking for a break.

Yes, they all worked fine until Friday (fairly new purchase but not had any problems with them before). What might a break look like (sorry, real novice!).

snapped solider join on back of lamp?

wire loose somewhere....

or just a failed LED light.... (one way to see is go out at night and see if the non working lights have a very dim LED or up close, thats normally a sign of a failed unit.)

other ways to test is to use a multimeter to test for 12v at each lamp in turn....

maybe post a few pics of night time with lights on?

can you take a light down to check?

are they cut into the roof? . . . or just screwed to the underside of the roof?
