Morphology

safelight = safe + light (semi-transparent) = safe + light

The compound clearly combines 'safe' + 'light', but its specific technical meaning ('a light safe for light-sensitive photographic materials') is domain-specific and may not be obvious to all learners.

Etymology

Safelight comes from the simple parts safe and light and refers to a dim lamp that is 'not harmful' to undeveloped film or photo paper. That's why a safelight, often red, lets you see in a darkroom without ruining the pictures.
