Right on John...also the oscillating rear end light worked the same way..On Zephyr type trains or round end obs cars the light was built in. In heavy weight or vestibule type LW cars the "portable"..it was pretty heavy light was hung on the gate across the vestibule opening and came on via a tail hose connection with the emergency air application or could be turned on at appropriate times by the flagman when protection was required under Rule 99...Although the rules always carried the disclaimer that the oscillating light or ABS signals did not relieve the flagman or member of the head end crew..could be fireman or brakeman...from "on the ground protection".

Its main purpose was to warn opposing trains on double track that the train may have jackknifed when it went into emergency. It could also be turned on manually.

Having never seen these locomotives operate, I don’t know if both or only one of the lights oscillated. If only one, which one? I’m installing a DCC decoder in early P2K models, and I need to know how to do the Mars lights. Any and all help appreciated.
