Fog signals went. Lightships went. Most manned stations went. Range lights largely did not, and the reason is worth understanding, because it is not sentiment and it is not inertia.
Satellite positioning tells a vessel where it is to within a metre or two. That is superb for knowing your position on a chart and considerably less superb for knowing your position relative to a channel that was dredged last spring, silts unevenly, and is marked on a survey that may be eighteen months old. The precision of the fix is not the limiting factor. The currency of the chart is.
A range does not have that problem, because it is not describing the channel. It is the channel. If the authority moves the line, it moves the towers or relights them, and the information reaching the bridge is correct the moment the work is done.
There is a second argument, less often made out loud. A range fails visibly. If a lamp is out, you can see that a lamp is out. An electronic system that is confidently wrong looks exactly like an electronic system that is right, and the history of groundings in well-charted water is substantially a history of people trusting a screen.
So ranges persist in commercial ports, on river approaches, and anywhere large vessels move through tight water. Many have been rebuilt in steel lattice, unlovely and entirely functional. A reasonable number of the original masonry towers are still doing the job they were built for, which is a rarer thing in this field than it sounds.
