JR Locomotives used for Push & Pull

As u can have locomotive leading and 2 box cars and a loco on the rear. the locos class lights are not coming on. is there a way to make the rear light apear in the trailing postion ?

No, that isn't the intended function of that feature on that particular locomotive. The class lights not coming on on the rear isn't an problem with the engine, it's just not how it works. Class lights are for the front of the lead loco to indicate several things depending on color.

try adding this tag in the extensions container of the config
class_as_mark "1"
this will make the class lights act as marker lights by switching on red lights if the loco if on the rear of the train
