This business next door put up some floodlights facing directly at my apartment

I can't even walk into the living room without shielding my eyes. This shit is not okay.

You should get a hold of whoever is in charge and calmly tell them that their floodlights are directly going into your apartment and if they could redirect the lights.

You should burst in with no shirt, foaming at the mouth, and scream "ME NEED LESS LIGHTS"

I know a guy who can throw some rocks at the floodlights for you.

Where I live, there is a city regulation against that.
Usually, city regulations are easily accessible on the internet.

After you verify your city's regulations, get solid proof of your claims, installing multiple security cameras in and out of your dwelling is a good way.

After you get solid proof, have a little chat with the owner of the business, enjoining him to stop immediately or you will start legal actions against him with the multiple hours of footage you already have.

Whatever his answer is, yes or no, you still make a complaint to the city for them to send an inspector to his business, this way he'll know that you don't fool around.

Works everytime.
