Yes I have just checked that out myself. There is also a high level brake light; and I think the two auxiliary lights at the front are fog and not spots - they would not be powerful enough to drive on.
I must say that I think the single rear fog, and single reversing light are totally inadequate; can I have some further opinions on this please.
Yes that is correct. Reverse on the left, and fog on the right. Also remember you will need your headlights on in order to test the rear fog light. I would suggest that when reversing you put the fog on as well, not that that will improve vision.
