I have the MTH moving backlit sign shown below (MTH #60-1337). It uses a 7" diameter florescent light bulb ring which is about a 1/2" in diameter. My bulb blew out and I am trying to replace it. MTH does not list the item on their website and there are no markings on the bulb so I have no idea what bulb I need.
Anybody have one of these or have an idea regarding what bulb it uses?
