Street light is on all night - shines into park homes and is positioned above stream

The street light was broken for a long time but is now fixed. It shines directly over a newly cleared stream which has grown bright green algae. Several trees that blocked it have also been cut down. The light shines into the park homes causing annoyance. It is not over the road because it is attached to a post so it is in the wrong place to be useful. It would be better turned off again - it does not serve an obvious purpose.
