Could pulsars really act as "lighthouses" to help in interstellar travel?

I was reading an article that said pulsars could be used in the far future, by travelers, by acting as "lighthouses" in space and aiding in interstellar travel. In a galaxy wide civilization, would this be still necessary or beneficial, if they had a method of faster than light propulsion?
