Solar powered traffic lights are becoming more common as a sustainable alternative to traditional traffic lights connected to electrical grids. They are well-suited for areas without existing power infrastructure as they are powered by batteries charged by solar panels. They have advantages over traditional traffic lights such as being easier to install and reinstall, having independent power supply from solar energy rather than electrical grids, and not requiring cabling which increases security. Solar powered traffic lights also provide benefits like continuous signal monitoring and status checks via SMS. They can conveniently power pedestrian crossings and alternate traffic controls as well.
