Thanks for the link, breezinup, but that thread and the video addresses a different problem with the backup light (on the right under the piping in my photos). I set up my three FA’s with separate ID’s, so the various lights in my lash up work appropriately. As for an assembler error, I don’t think that is the case. This isn’t the best pic, but I think you can see that there are two small holes allowing the wires to the light to pass through the shell, so it would be impossible to pull the LED back into the shell.
In addition, I believe that I have all the lights that I should on the engines 
And just to cover all the bases, I tried the Aux 2 button, and the cab lights, head light, and backup light (if illuminated) all turn off, but these odd LED’s stay on. To quote the King of Siam, “is a puzzlement”!!!
Hopefully someone from Lionel will chime in with some info.
