Morphology
The sense 'to scold or reprimand someone forcefully' cannot be directly derived from the literal meanings of 'light' (set on fire/illuminate), 'ass' (butt) and 'up' — the phrase relies on slangy, metaphorical imagery. Because it is idiomatic and potentially ambiguous (can also imply violent attack/‘shoot’ in other contexts) a B1 learner knowing the parts would not reliably infer the intended meaning without prior exposure.
Etymology
The phrase light someone's ass up may come from the image of someone being suddenly 'lit', as if set on fire or attacked, so the verb light suggests a fierce attack on the person. So this strong picture became a way to say 'to scold or reprimand someone forcefully'.
