Provide lighting: Street lights are essential for nighttime driving, and the brightness, color temperature, and illumination angle of street lights are key factors affecting driving safety. Street lights can illuminate the road ahead and the surrounding environment, allowing drivers to see the surrounding situation more clearly and reducing the occurrence of traffic accidents.

Enhanced landscape: In addition to lighting, street lights can also enhance the urban landscape effect. They are designed in various shapes and colors, which can become a beautiful scenic line on urban streets and even become one of the city's landmarks.

Enhancing a sense of security: In cities, streetlights can provide a sense of security. Bright lights can reduce the occurrence of criminal behavior and make people feel safer. At the same time, street lights can also provide lighting for citizens who engage in outdoor activities at night, improving their quality of life.

Energy conservation and environmental protection: With the increasing shortage of energy and the improvement of environmental awareness, the design of street lights is also paying more attention to energy conservation and environmental protection. For example, some street lights use LED technology to more efficiently utilize energy and reduce energy waste.

In short, street lights play an important role in improving traffic safety, enhancing urban landscape, enhancing safety, and energy conservation and environmental protection.
