Pretty large generation gap there. It also looks that the 12"x24" lights have LEDs in them too.

Thank you, SPL.
Are railroad bells not 10VDC?
The lowest voltage bell in that catalogue is 24VDC.

I'm not sure why the lowest voltage listed is 24v, but I do know that most crossing bells operate on 12v DC.
My recollection, from when I was a little boy speaking with a signal maintainer and seeing the fascinating glass-encased relays on springs, was that the track batteries in series total about 10 volts. Train detection voltage was 1/2 volt.
(This was Lewistown, PA about 1959.)
