Morphology

lightbulb = light + bulb (transparent) = light + bulb

A straightforward compound where 'light' + 'bulb' directly denotes a bulb that produces light; meaning is obvious to learners.

Etymology

Lightbulb is simply light + bulb, and bulb brings to mind a round plant part like a flower bulb or an onion. So a lightbulb is the round glass object that makes 'light', which is why the word means the electric lamp you put in a lamp or the ceiling.
