I am with macguyver on this one. Having searched through all the sets on Klickywelt's Datenbank-Setinhalt, I couldn't find a red lantern. But several of these early sets have the chrome lanterns. So I checked my spares and found two with worn chrome, one with white plastic underneath and one with red:

For some reason, quite a lot of early chrome parts have a red plastic base. Sometimes the chrome wears off completely. Maybe there were red lanterns, but I think it looks likely that they were formerly chromed. Any traces of chrome anywhere on your red lanterns pingo or tahra?
