Pack of 10 battery-powered train tail lamps with red jewel reflector.
This style of compact, battery powered tail lamp was developed in the 1970s for Freightliner trains, where oil lamps, exposed on the end of a flat wagon, were being blown out. Following successful testing these electric lamps steadily replaced the traditional oil lit type for all trains during the 1980s and are the standard train tail lamps in use today.
