Why was Leonard mead house the only one with lights on in pedestrian?

In Ray Bradbury's short story "The Pedestrian," Leonard Mead's house is the only one with lights on because he is the only one who is awake and at home at night. The story takes place in a futuristic society where everyone stays indoors, glued to their televisions and other forms of entertainment. Mead, on the other hand, enjoys walking at night, which is seen as an odd and even suspicious activity by the authorities.

The contrast between Mead's lit house and the darkened ones surrounding it symbolizes his individuality and his rebellion against the conformity of his society.
