Solar road studs are innovative applications of solar energy technology in the field of traffic safety. They are environmentally friendly and energy-saving, with high visibility at night, and have many advantages. However, solar powered road studs also have some disadvantages, which limit the popularity and application of solar road studs to a certain extent. The disadvantages of solar road studs, such as excessive dependence on sunlight, high cost, limited battery life, and the need to improve pressure resistance, also limit the popularity of solar led road studs to a certain extent. However, with the continuous advancement and development of science and technology, we believe that these difficulties will be overcome one by one, and solar powered road reflectors will play a greater role in the field of traffic safety.
