Typically, adjacent house are on different phases - so a fault which
affects just one phase (at your substation) will najjer the supply to
roughly every third house. I don't know how in practice streetlight
supplies are taken from the local substation - p'raps someone who does
will pipe up real soon now ;-)
Could it be that at various points around the town a single phase supply
is handed over to the light dept who wire their own lampposts.
It won't be a very big load.
