Morphology
The phrase 'anchor light' is a literal, compositional combination of 'anchor' (mooring device) and 'light' (lamp), so a B1 learner who knows both words can infer it is a light associated with an anchored ship used to signal that it is at anchor. This noun+noun pattern denotes purpose/association rather than an idiomatic meaning and is cross-linguistically common, making the expression transparent.
Etymology
Anchor light comes from the simple idea of a light shown when a boat's anchor is down. When a boat shows this light at night, other boats can see it and know the boat is 'at anchor', not moving, so today the term means the warning light a boat shows while anchored.
