I picked this light up recently at an antique store for $12. It has a 5 diameter and is just over 5 inches tall. It has a removable magnetic base so all or any excess power cord can be stored inside it. It is a self-contained strobe with a single flash pattern. The light isn't very bright, but it was unique looking and priced right for an antique store. The amber dome is plastic. I couldn't find much information about it online. Does anyone else know anything about these lights?
