Morphology
The meaning is partly derivable from the parts: a B1 learner who knows 'running' (operating/underway) and 'light' (a lamp/signal) can infer this refers to a light that is on or used while a vessel is moving. However, the specific maritime/navigation function and regulatory sense (position/direction lights on boats) is specialised and not fully predictable from the constituents alone, so prior exposure helps.
Etymology
Running light comes from the simple picture of a running boat with a light fixed so people can see where it is and which way it is going. So today it means 'a light carried on a boat to show its position and direction'.
