At the entrance to the Enfield Public Library there is a rectangular shaped (large) light on the same pole as the street light I believe. This large light keeps coming turning on and off approx. every 5-7 minutes; stays on for perhaps 30 -45 seconds and turns off again. The light appears to be malfunctioning. I don't know who owns or controls this light but it has got to be costing extra money to run it if it keeps going on and off. Please see if you can do something with this issue. Thanks. p.s. Personally I don't see how that light is necessary anyway. There is a streetlight right there that is working fine. Seems like a waste of money to me.
