When using http://www.openstreetmap.org/ when I zoom in on a city I can see street lights on a junction. However they are not clearly visible due to their small size and the numerous other small symbols.

I would like to view every traffic light in a city to compare with this post which displays every traffic light in a Dutch city.

Is there a way of filtering the key to only display traffic lights, and when zoomed out?

you write "street lights" in the title. But you are not referring to lighting, right? Maybe change this to "traffic light / signals" then.

Yes, this is possible. For example by using the Overpass API or overpass turbo.

Here is an example using overpass turbo:

<osm-script output="json">
  <union>
    <query type="node">
      <has-kv k="highway" v="traffic_signals"/>
      <bbox-query {{nominatimBbox:Dresden}}/>
    </query>
  </union>
  <print mode="body"/>
  <recurse type="down"/>
  <print mode="skeleton"/>
</osm-script>

It will display all traffic signal for the city Dresden. If you choose to use the Overpass API instead, you will have to replace the {{nominatimBbox:Dresden}} keyword with the bounding box of the corresponding city, because nominatimBbox is an extension specific for overpass turbo.
