How does a lighthouse helps ships navigating?
In: Engineering
They were basically giant hazard warning lights. They were built where ships were at risk of running aground or afoul of especially shallow water. So you’re out at night (especially in a time when electric illumination was rare or didn’t exist) and you see one light off in the horizon and you at least know to keep your distance because that’s where the shore begins and you don’t want to run into it.
Or if you’re looking for a port that can be a sign too.
Today with the advent of radar they aren’t as effective anymore and ones you might visit aren’t functional anymore.
