Fuck off shill. Ignore this guy, you only need lighthouses if you're in a "cloudy" magnetic zone. It's why they're called lighthouses to begin with, a clean area where the magnetic field is consistent and unchanging means you don't need it.
Stuff like volcanoes, anomalous areas like the bermuda triangle, near nuclear power plants(like right next door) and neutron stars are examples.
