What a great solution if you don’t have house numbers on your wall. I included a night time  day time view of the address post. It comes with a battery for energy back-up to the solar device. It’s very bright at night, you can see the numbers very clearly. I have it a 4-star rating for innovation, but because the device is made of plastic and is a little flimsy when driving it into the ground, I could not give it 5-stars.
But it does do the job of a lighted house address post.
