Nighttime visibility refers to how well objects can be seen in low-light conditions, such as during the night. Factors affecting visibility include the presence of artificial light sources, like streetlights and car headlights, as well as natural light from the moon and stars. Weather conditions, such as fog or rain, can also significantly reduce visibility. Good nighttime visibility is crucial for safety, especially for drivers, pedestrians, and cyclists. It helps prevent accidents and ensures that people can navigate their surroundings effectively. Various tools, such as reflective clothing and flashlights, can enhance visibility during nighttime activities.
