Hello.
Changes made in this edit need to be fixed.
You added "lamp_mount=mast" tag on this streetlight. However, as documented on https://wiki.openstreetmap.org/wiki/Key:lamp_mount "=mast" is not one of the documented tag values. 
And finally, "support=street_lamp" is not one of the documented values from https://wiki.openstreetmap.org/wiki/Tag:highway%3Dstreet_lamp
