I stumbled across this old Ebay posting for a Vintage Equality Roto-Flasher Emergency Light. This photo looks to be the same as my very first emergency light. I ordered it from a Johnson Smith novelty catalog. There were two versions. One that ran on C or D cell batteries and this one that plugged into the cigarette lighter. It came with red, amber and blue domes. The blue dome looked more purple to me. The suction cup base was not very reliable as I recall. The light was only as bright as a flashlight (not as bright as real emergency lights of the day). I think I bought mine in the late 1970's or early 1980's. Does anyone else remember this light?
