Illumination enhances your outdoor spaces, but it's also important for safety and security—and these are all good reasons to brighten up your yard. Start by purchasing low-voltage landscape lighting, which plugs into any outdoor GFCI outlet. Plan the placement of the lights, dig a narrow trench to bury the cable, then plug in the transformer. Then, make the electrical connections and install the lights. If this all feels like too much effort, think solar—lights that have no wiring are snap to set up!
