Morphology
The meaning 'a circuit of wiring that supplies power to electric lights' is directly and compositionally derived from 'lighting' (relating to lights) + 'circuit' (a route for electric current). This noun-noun compound follows a common, cross-linguistically transparent pattern, so an average B1 learner who knows both constituents will readily infer the intended meaning.
Etymology
The term lighting circuit comes from a simple image: a circuit is a loop or path of wires that brings electric lighting to lamps and bulbs. If that loop 'trips' or breaks, the lights lose 'power', so the phrase means the wiring that supplies power to the lights in a room or house.
