Origin

The word comes from the famous lighthouse of Alexandria, known as the Pharos. This name comes from Greek Pharos, the island where the lighthouse stood. The term passed into Latin as pharus, then into French as phare.

Over time, the name of that one lighthouse became the general word for any lighthouse. Later, the idea of a strong guiding light led to figurative uses, and then to the modern use for vehicle lights.
