One of the primary causes of light pollution in Aïn Oussera is the extensive use of street lighting throughout the city. Street lighting is essential for ensuring public safety and security, but the intensity and placement of these lights can cause significant light pollution. In Aïn Oussera, street lights are placed along major roads and in residential areas, and their intensity is often higher than necessary, leading to a bright and overwhelming glow that can be seen from afar.

Many residents keep their lights on throughout the night, even when they are not using them, contributing to the overall brightness of the city.
