Some street lights are suspended through wires instead of being attached to. I’ve mapped these with man_made=utility_pole and utility=street_lighting but I have I have no idea how to tag the wires themselves, especially because I also draw a line for better placement of the lamps themselves anyway and the effort feels a bit wasted.
Hello
These are suspended street lights, sometimes in a row and fed by a catenary. It has nothing related to utility poles unless the catenary or the suspending wires are anchored on such poles (it could also be anchored on building walls with no utility poles).
In case of utility poles, they should be combined with utility=street_lighting, not utility_pole=*.
The light itself should be taged with highway=street_lamp and corresponding attributes (lamp_mount=suspended particularly)
I don’t know how the wires should be taged yet but it reminds me the discussion we had about catenary masts. The same situation is depicted there with catenary_mast:supporting=head_span. This tag goes on the pole supporting the wires.
The suspending wires may be related to a special kind of portal as well (supported features are located between the legs) but it looks overkill.

I’ll note that the most useful information from your post is that I accidentally typed in utility_pole instead of utility in the OP (and for that matter, the masts I already placed already used the latter).
What a strange way of apologizing for a mistake. Did you notice that the world does not revolve around your ego and that @InfoReseaux was trying in good faith to reply what you have posted? Some of us are more polite to our AI agents when we make a typo than you are to a human.

man_made=guy_wire was proposed for “guys” Proposal:Guy wire - OpenStreetMap Wiki
(if you want a laught) Tag:man_made=guy - OpenStreetMap Wiki
Could be generalized to the ~500 man_made=wire + wire= =guy vs =suspension here man_made=wire | Tags | OpenStreetMap Taginfo
Mostly used over Helsinki tramways. Seems to be the supporting span wires from the density.
Interestingly ~60 standalone wire=support in Germany wire=support | Tags | OpenStreetMap Taginfo
Only 1 man_made=support_wire now, if it needs to be clarified man_made=support_wire | Tags | OpenStreetMap Taginfo
Problem is they may either be run free, or along with other cables, even differing on each span. Those need to be some power= + communication= ?

Here’s how I would map them.
The lights:
highway=street_lamp
light_source=lantern
light:support=wire
(plus other applicable tags: light:tilt=-90, light:method=*, …)
The wires:
man_made=wire
The poles:
man_made=utility_pole
utility=street_lighting
(plus other applicable tags: material=*, height=*, …)

This is pretty similar to how I sometimes micromap the wire-mounted traffic signals that are ubiquitous in some parts of the U.S. The one thing I’ve done differently is to tag the span wire as power=minor_line. man_made=wire would more precisely identify the span wire, though I probably would at least combine it with power=minor_line. From what I’ve seen, the electrical supply usually runs the full length of the span wire. Even if that isn’t the case, I’m unlikely to be able to tell which end it’s coming from by looking at street-level imagery.
A bare man_made=wire would be a good option for a high-tension wire that only holds up traffic signs:

Surveyed Treglio last Friday, done in 15 minutes, all captured on kodakchrome,
this one and so many with aerials usually lost in the deep shade of the narrow alleys**. light type led (about 100% of streetlamps are led here), light mount=suspended, so my custom preset offers as choice which is where I’m laeving it at.
(and whether these are straight, bend or slanted, also in Treglio, not going to loose nanoseconds of thought on that, given them the straight label in kneejerk… no one asked for the angle, yet, albeit we got the tilt tag, most -90 to -80 degrees. Used to do that but nowadays leaving that to the aficionados after re-survey.
** suspended because pole mounted would not last very long. The village has many dozens of wall art pieces, 3 in the first. Not mapped.
As errata, layer=1 since else risking the complained that the streetlamp is crossing the way, though JOSM and ID are perfectly fine with them being tagged as node on the road.
After taking a closer look at suspended lamps, you usually can see which wires carry power and which ones don’t (mostly by the extra cables) which does mean that using power=* throughout (I don’t know if minor_line might be overkill because I usually thought of it as a regional power distribution instead of a local street lamp) is incorrect for micromapping purposes but does work as a basic compromise where it really isn’t obvious.
Sure, it doesn’t have to go all the way across if you can determine the endpoints more precisely. I’m usually working with only aerial imagery or at best very blurry street-level imagery.
It does get a bit into the weeds with a street lamp. I just wanted to draw a parallel to traffic signals and other things that can have cables running into them. Originally I would map this kind of cable leading into pole-mounted emergency=sirens, often going right over a street, to indicate whether and how the siren connects to the power grid versus being battery-powered. I also daydream that information on overhead electrical cables could potentially help emergency crews and the public find safe routes after a major storm or earthquake.
Similarly, I’ve also been mapping service drops leading into residential buildings. I was under the impression that, to the extent that we even map these lines, they tend to be tagged as power=minor_line. This proposal for the endpoint of such a line doesn’t say what to use for the line itself, but I assume that it would just reuse power=minor_line, even if it doesn’t form the backbone of any distribution network.

power=minor_line and power=cable are valid for street lighting.
As live wires running along support wires are insulated, power=cable would be more suitable than power=minor_line. It would be ok to combine it with utility=street_lighting as well.
This is a valid point, I will take care of this.
I agree: minor_line for uninsulated wires and cable for insulated ones.
That should also extended to service drops themselves and investigate if it’s valid to tag them with power=terminal. More details on RFC thread.
