I couldn&#x27;t agree more that more attention should be paid to where the lights shine and how they affect night vision, but they don&#x27;t even have to direct any light upwards to make It bright enough to affect sleep on the floors above.<p>Even with all the light emitted downwards, a narrow street with bright and closely spaced streetlights means that there&#x27;s enough reflection off pavement, cars, building facades and windows, etc. that a huge amount of light is reflected back above the lamp.<p>Depending on where you and the trees are relative to the lamp, the leaves may lessen or exacerbate the effect. And overcast nights make it even worse because you get a second dose of reflection (from the entire metro area, much of which has been similarly &quot;upgraded&quot; to Hollywood interrogation spotlights... I mean, LED streetlights.)<p>It&#x27;s not as if anyone was claiming this neighborhood was dangerous or scary to walk in at night. If I wanted to live in Times Square I&#x27;d live in Times Square.
