Clear, acrylic night light. My cat and I think it is so pretty. The color of your wall will show thru, so doesn't always have to be clear. My bathroom walls are white, so it casts a brighter light. It has a bit of weight to it, so it tends to slightly tilt forward in my wall outlet which being up near my medicine cabinet, I feared it would loosen and fall. But a tiny stretch of the prongs fixed the problem. I really like it a lot. Amazon has a great selection of night lights at especially good prices. Can't find them in stores, and pretty ones are very overpriced in gift shops.
