Try the usual fix - press/touch the central light for 2-4 seconds until the lights flash twice.
This is the interior lighting reset procedure.

 

This morning, after 2 days, everything went back to normal without surgery. I do hope this is the first and last Gremlin I spooked away.

 

 

Not a requirement and I don't know of any other car brand which does the same, although all Jags have been like this since around 2008 I think.
With Jags it's just that any time you pull one of the interior globes (for example to replace it) you have to do this reset before the interior lights work properly again, that is they turn on when you open a door and turn off (after a delay) when you shut the door.

 

I don't think it's a 'reset', it just switches the lights between coming on when the door opens vs. not coming on.
