PL Signals

[NW Mailing List]

I have a question on N&W's position light signals.  This is a  small detail 
but an important one for me because I am working to restore such a  signal to 
the all amber configuration.  I have seen some signal light heads  (for lack of 
a better way to identify the actual individual light things) that  have a 
colored cone protruding out and a clear lens behind it.  I wonder  when this 
practice started or was it that way all along?
