This is a nightlight with multiple colors and rotation of colors. It also has a lighthouse in the center. The glass is laser-etched.When you trurn on the nightlight, you sill see bursts and transitions of different colors in the middle of the glass block, so you see the beautifully cut glass. Just lovely and unusual! This is one of two such nightlights we are selling. We have another one listed that is 6x2x2, if you're interested in that. The nightlight takes 3 AA batteries.Thanks for looking!
