To be clear, the SP GS-4 class northerns were delivered from Lima Locomotive works with Mars Lights (no red feature). No other steam locomotives on SP had Mars lights except those GS-4/GS-5 steam locomotives, until diesels were delivered. The diesels all pretty much came from the factory with Mars or Pyle National Gyra-Lights.
