Morphology
The meaning depends on a metaphorical use of 'light' (= understanding, guidance), so a learner who recognises that figurative sense can compose 'by + one's own + lights' as 'according to one's own judgment'. However, the non-literal sense of 'light' (and the slightly idiomatic/plural phrasing) is not guaranteed to be known by an average B1 learner, so comprehension is only partial without prior exposure.
Etymology
By one's own lights comes from the picture of a person moving by their own small lights, so they see the world in their own way. So to act by one's own lights means to do something 'according to one's own judgment' rather than following others.
