Ford Focus 13 — interior lights not switching off once locked

Turned out it was the door lock.

Thanks. It only happens when you put it on so I'm assuming it is by design.

The timeout on them seems to be about 10 minutes anyway before they turn off if they are left on manually.

Ah, really? That's answered it then, thanks! You would think the same feature that does this for opening the doors would do it for this too so it makes sense.
