Observing tail lamps

[K.o.R]

Question related to tail lamps: Why, when running with locos at both ends of a train or as a convoy of several locos, do they often stick a tail lamp on rather than using the rear loco's own red lights?

Two suggestions:

Would the driver know if the lights on the rear loco had failed? Does any through wiring indicate such a fault?

Possibly - more basically - because it is a train and that is what is written in the rules for a train.

The rear loco will be dead. Putting that loco's tail lights on would run down its batteries.
