HO CA-8 Early Caboose with Lights & Sound UP #25511

Caboose marker lamps serve as a way to indicate the location of the rear of the train, especially at night. They marked end of the train. so another train could see it and not rear end the train. Consequently they normally only had two on a caboose, mounted to the rear. They had brackets to hold them so they could be moved from one end to the other if there was a change in the position or the direction of travel of the caboose. They were normally removed once the caboose was no longer part of the train. Back when markers were "Hung" on the rear, when a train would get in the clear in a siding, the red would be turned in to the side of the caboose to show green to the front and to the rear to show the train was in one piece and in the clear.
