Lights
First encounters
After mapping street lights and poles and then Seamark lights I looked deeper into how to map light mostly light that is made my man and is in a consistent location. The addition of mapping lighting in Street Complete made this question greater with a tag like lit=yes this is great and all but not very descriptive if talking about a street or a way that may have puddles of lights at each street light.
Beyond
This has taken me to the point of looking at adding night lighting to the tops of power poles or rotating beacons on top of airport towers. These sorts of things could be found it mapping seamarks but for the most part is not appropriate for Open Sea Map. This is the line between it exists and there is a standard to make the light show and to add the correct tags to describe its sequence of flashing but it is not a seamark light but there is overlap between. There are power pole or tower lights that do show on nautical charts.
Thoughts and reflection
Are we mapping with enough detail, is it easy for a first time mapper to contribute, and are we mapping for the renderer? Anything I missed below?
Lit:
Highway:
flashing_lights=* highway=traffic_signals crossing=* highway=street_lamp
Railway:
railway=level_crossing railway=signal
Man_made:
Seamark: osm.wiki/Seamarks/Lights osm.wiki/Seamarks/INT-1_Section_P

mapping for renderer is fine, lying to renderer is wrong
mapping correct data in standard format is fine, mapping fake data to force specific display is wrong

crossing:light=andlight_source=are good stuff. There’sluminous=to show a feature itself is emitting light, unlike the 3rd-personlit=.
