Morphology

light-bulb + moment

The meaning 'sudden realization' is metaphorically derived from the image of a light bulb switching on (illumination of understanding) combined with 'moment'. Because this is a figurative mapping rather than a strictly compositional meaning, a B1 learner who knows the parts may often guess the sense but not reliably without familiarity, so it is partially transparent.

Etymology

Light-bulb moment comes from a common picture of a light-bulb turning on above someone's head when they get an idea, like in cartoons. So it means 'a sudden realization' when something suddenly becomes clear.
