[Tagging] Difference between lighthouses and beacons

Ok, the discussion at least came to an agreement that this:

is not a man_made=lighthouse. We have A LOT of those mapped as lighthouses
(I think the majority of that tag is on the wrong element). One reason is
rendering, and we have to start rendering something. The question is what.

I looked at man_made=beacon. Taginfo says we have about 7 000 of those, and
the wiki shows something that resembles what we are talking about, but not
quite:

https://wiki.openstreetmap.org/wiki/Tag:man_made%3Dbeacon

Maybe just start rendering seamark=beacon? We have only about 2 000 of
those, but we have 40 000 seamark:type="beacon_lateral" or
"beacon_isolated_danger" or "beacon_special_purpose". We can add
seamark=beacon to those.

The icon would be something like man_made=lighthouse, but thinner.
