As for interior bulbs: in the overhead light units (and a few other locations around the car) I have fitted Ring 501 LED 12V W5W 4000K bulbs. My 2011 MY car had push and turn bulb fitment in both ceiling light units, so I also bought a pack of Ford adaptors that allow use of W5W bulbs. That works perfectly. Initially I had all those bulbs glowing very faintly all the time, but, after changing one bulb, that stopped. A faulty bulb I think.
Interestingly my 2013 C30 had what appeared to be identical ceiling light units that had modern W5W push-in fittings as standard, so later cars should be easier to update.
