Need help IDing part

[HELENT]

Can anyone help identify this back up light? No markings. No numbers. No nothing. Approximately 3" across. I really only need the lens. 46 Ford Super Deluxe Coupe

I have one that looks like yours, but it has a red lens with STOP on it. If I remember correctly I bought it back in the 50's and never installed it, probably from Western Auto Store, or Advance Store. Not sure about clear lens, they could have been made to interchange the lens for either back up or stop. Hope this helps.
