The World Book Encyclopedia notes: “Mariners determine which lighthouse they are seeing ​ — and therefore their location — ​ by observing the characteristic of a lighthouse and consulting a light list. ”
„ The World Book Encyclopedia ” märgib: „Jälgides majaka karakteristikuid ja uurides majakate registrit, teevad meremehed kindlaks, millise majakaga on tegemist – ja selle põhjal ka, kus nad parajasti asuvad. ”
