Dress up the view out your back window with these purple and red, solar, lily flower stakes for your yard. They don't need any wiring at all.
The petals are made of a durable outdoor-safe fabric and they're waterproof. There's a battery inside that gets charged by the sun. A sensor determines when the sun has gone down and the LED filaments come on and then turn off when the sun rises.
While they're on they slowly change shades so you get a variety of different colours from one set.
