Sidewalk lights are necessary for safety, but they also add greater dimension to your landscape after dark.
There are three main power options — hardwired, solar, or a combination of the two. Hardwired lights are usually dependable since a string of cloudy lights won't leave them dim. They are a little more difficult to install since an underground power supply must be put in. Although the power cords can lay on the ground between lights, buried installation is preferred for both appearance and safety.
