Surface Forms

Morphology

by + one + light

The phrase uses 'light' metaphorically to mean understanding or guidance and the prepositional pattern 'by one's X' signals acting according to a standard, so a learner who knows the constituents might infer a rough sense. However, the plural 'lights' as 'guiding beliefs' is somewhat literary/idiomatic and not an immediately productive composition for a B1 learner, making the relation only partially predictable.

Etymology

The phrase by one's lights may come from the image of a small lamp or an inner light that helps a person 'see' what is right. So, to act by one's lights means to do what you think is right.
