A lighthouse beacon is a light that guides a vessel to safety, and so the streetlights were like a beacon to them, guiding them to safety and were were wonderful and welcoming.
Context: They never thought they would see streetlights again, but when they did they were wonderful and welcoming.
Hypothesis: Neither of them ever imagined that they would see streetlights from the dark side of a sewer grate, but there it was, like a lighthouse beacon to a fogged-in vessel.

Is the hypothesis incorrect? (Yes, no, or unknown)?
