has the light got its own itegral switch, or is it switched from a remote switch.
if it has a remote switch , start there, and test for 12v there.
if it has its own switch, then 12v supplies are generally "jumped" from one light fitting to another.check the nearest fittings ,and see if a wire has come loose there.

The first place to check is the 12 volt fuses as it may be just a blown fuse that needs replacing.

It’s the only light in van not working
Maybe it is the only 12 volt light in the caravan not working but it may not be on the same circuit as the ceiling lights therefore it will have an independent fuse. It won't do any harm anyway just to have a look at the fuses to eliminate the source of the problem as most faults are usually just a simple solution. Once the fuses have been checked then it's time to check the switch to see if that is faulty and finally the light itself and check that all the contacts are clean and secure. Basically it's a process of elimination before looking for problems with circuitry wires and cables.

My 2016 Quasar has the wiring circuit diagram in the owners handbook, try looking in your handbook. If you haven't got a handbook you can download a PDF version from https://www.lunarcaravans.com/help/handbooks-guides.
Your van differs from mine with it's fittings, so I can't make direct comparisons to assist further, other than say the low current drawn by LED lights is often too low to keep joints and switch contacts clean of minor surface oxidation, which can then lead to apparent failure of lights. I've had to tweak a number of mine to restore brightness or get lights working again!
It's bad practice by manufacturers (in general, not just caravans!) who don't choose the correct switch contact design/materials and connector types for low current devices (old fashioned bulb higher currents had a tendency to blast through any minor oxidation and keep working), simply substituting LED lights for incandescent or fluorescent units without matching the whole system to the current demand is poor sloppy design!
Good luck.

how are you checking for 12v at the switch? how many wires are on the switch?, to test for 12v at the switch you may need to run a long negative lead, back to the battery , or to a known good negative wire.
