I also have a picture of what would count for LOCAL/EXP signs on #9574. Click here to see it. (455K)
Notice that instead of a piece of glass, it's actually an LCD display. (it says LOCAL, and that's where an EXP sign would be.) Was this part of some kind of test project or something, to put LED signs on the Redbirds? (It most likely failed because the Redbirds still have the glass signs.) Does or did any other Redbird have this kind of sign? How did it work? Were they ever backlit similar to the LED destination signs on the R44, 46, 110A/B?
