We needed a night light for our daughter a few months ago, and really wanted a blue canary night light, but couldn't find one. So I made one! You can have one too!
The blue canaries are made by hand by me, here in Minnesota in the United States. They are attached to a commercially available LED night light base with a sensor eye, which is warrantied for life and uses only about $0.25 worth of electricity per year. The light dims and brightens as the ambient light brightens and dims.
