I had exactly the same problem a couple of weeks back. All or nothing with the lights made for some fun evenings coming back up the M23. Turned out that the headlight control box in the boot had burned out. For some reason it had also damaged a circuit the headlight switch.

Control box not a problem but sourcing a new switch was a 'mare as nowhere has them in stock and factory only assembles new ones on request (apparently)

I'd try the control box first but not sure of the cost involved as it happened only 3 days after picking the car up and the dealer sorted it for me.

The headlight control box....Hmmmm

Mine did this too. The problem is caused by the current generated by the lights being a little too much for the little connectors that have been used to connect the control box into the lighting circuit. The connectors dry out/burn out and the connection becomes unreliable.

This can be seen by removing the velcro panel above the fuel tank (in the boot) and locating the correct control box. There are two that relate to lights, and they should have a (handwritten) label on them to designate them.

Look carefully at the white connectors that are immediately obvious, and it is likely you will find your problem here.

A short term fix that I used until Joolz did the job properly for me was to use Alum Foil to make the connection bigger (and thus easier to form). The long term fix is to drill a hole in the control box, and solder the wire onto the circuit board directly.

Hope this helps

Cut off the connector on mine, cut away the plastic on the control box, used insulated female spade clips. good as new. It appears to be the connectors and not the box itself that cant handle the load.
