Morphology

red + light

The meaning 'a warning or signal to stop/proceed with caution' is directly derivable from combining 'red' (a color conventionally associated with danger/stop) and 'light' (a signal or lamp). This color‑signal composition is cross‑linguistically common and follows familiar traffic and warning conventions, so a B1 learner who knows both constituents will generally understand both the literal and common figurative uses.

Etymology

Red light is the red traffic signal at a road crossing; the bright red on a light tells drivers and people to stop, so it means 'must stop'.
