Not sure about Scotland, but in the US, most of those would be [technically] illegal for use on a boat capable of more than (as I recall) 6mph. You'd need to look at the coding on the actual light fixture (or rather see what the manufacturers have listed as the coding, as it's probably not on the fixture itself.)
That said, I have never seen anyone cited for using lights that operate, but are not up to spec for their particular vessel. I have seen vessels cited for lack of lights.
A simple 1.5 or 2 meter pole with white on top and sidelights a meter below would be legal (though you would need to pay attention to orientation.) Light mounting positions on small boats tend to be rather flexible.
