Coupe interior lights

[Benderloch]

Hi All

When I ran a scan on my car recently it showed that an interior light had an open circuit All the lights seemed to be working, then I wondered if the unit on the headliner contained lights. So I removed it. I assume it has something to do with the alarm system and it does appear to have 4 lights which certainly do not light.
Any suggestions. Then to add to my troubles I can’t for the life of me get the cover back on the head lining.

Any help greatly appreciated.

Thanks
