I think these are from Shiloh Signals. I do not know if they work, since I don’t know anything about them and don’t want to burn them out. $25 plus shipping?
Bob,
My Shiloh signals in custom ordered years ago had a small resister wired in next to the signal head led so you could use 9 volts? You could run a ohm meter check on the wires.
I would like them, Bob. How to give you address to figure shipping?
