Morphology

light-headed = light + head (semi-transparent) = light + head + ed

The composition 'light' + 'headed' is literal, but the sense 'silly' is a figurative/metaphorical extension rather than a direct, literal meaning.

Etymology

Light-headed comes from light ('not heavy' or 'not serious') and headed (about the head); a helpful way to remember it is to think of light-hearted. If your head is 'light' you are not full of serious thought, so light-headed can mean 'silly' or giddy.
