It is even easier and cheaper to mount a switch close to helm station. Anything automatic will become less automatic in time.
To make systmes run automatically is not simple neither cheap.
This non automatic systme is very easy to operate and reliable.

> What if a tricolour was mounted on a bearing on the mast head, with a short strut attached to the light. Tied to the strut is a thin stretchy (to accommodate mast bend) line which is attached to the now bow. When you shunt, the line is undone and reattached to the new bow, rotating the light independantly of the mast.
