What is the ruling on staying up late and watching television at high volume with disturbing light, given the presence of housemates and neighbors who are bothered by that?

What the questioner mentioned regarding harming neighbors falls under causing them damage, which is one of the major sins. Harming neighbors with noise and clamor, whether by raising the sound of music and entertainment, or quarrels, or noisy children playing, or knocking on doors, or sounding annoying car horns, especially during resting hours, is reprehensible. Its ugliness increases if the neighbors need rest and sleep. The questioner is advised to repent, seek forgiveness, ask for pardon from their neighbors, cease harming them, and be good to them.
