Burford Duo internal lights

Hi. I have a 2017 Burford Duo. Today for the first time the LED lights above the storage cupboards in the lounge have come on. The manual describes them as background lighting but doesn’t mention any switches.
I am not certain what I have done for them to come on but would like to switch them off !!!
Another point now I read the manual is that is mentions the LED reading lamps in the bedroom and lounge can be dimmed via a push-push switch, do these exist as I can’t find the switch!
Thanks for any help.

Hi Ken
In our van it is a split switch which is just near the hab door but in rear lounge models it was near the tv point
