I'm really not sure what you don't understand about the word DRAW or
about the fact that the total number of positive votes exceeds the
total number of negative votes. But another fact is that your opinion
does not alter any of these facts.

I wouldn't call an approved proposal, which hat 200K applications so
far (the same order of magnitude as highway=street_lamp), "not working".

Yes, there are indeed, I do not doubt that. It was just a general
remark that this tag may also be misinterpreted (which probably
applies to many words, one needs to choose carefully in any case).

Sounds reasonable to me, but also raises the question: If something is
tagged as man_made=pole + light=* or the like, and there are
additional tags, what do these tags apply to? This is the same problem
as with tagging tourism=hotel, amenity=restaurant, and then something
like wheelchair=yes all on one node - to which does the latter apply?
In this example one can usually separate the hotel and the restaurant,
but for a street lamp, one would probably want to attribute the pole
and the light source to the same node, as they belong to a common
structure.

> What would be other values for this new key?

I guess that would be things that I placed under "lamp:type" in my
proposal. For example, just some quick ideas:

- - "lantern" (which I actually like more than the lamp:type=street_lamp
in my proposal, since it takes the "street" out of this name, and
would be a lighting for maybe a railway, an area... or a street)
- - "signal_lamp" (yes, I checked the term - see wikipedia)
- - "warning" (a hazard warning lamp)
- - "aviation" (like those lights at an airport runway)

What about light_source? This is also not used so far, and it gives a
rather accurate description of the object being mapped. Something
ending in _type sounds more like a subclass to me (as we don't tag
highway_type=*, but highway=track, tracktype=*).
