No Tail Lights On Ice 3

I don't have the red tail lights at the rear when I use the ICE 3 on Kassel-Würzburg. Am I the only one ?
I play on Xbox series X.

 

I am having the same problem too on PS5

 

I played with the ice1 earlier and it was running tail lights both ends. I set headlights to bright, no different, however, I didn't have time to poke through the buttons and screens when k played so im inconclusive whether there is something in addition to the lever on dashboard

 

I just saw that it only happend on tutorials and scenarios, not services...

 

Is there a button or lever for that ? I though it was automatic...

 

I have been having the same issue here but I have found out that the headlight switch in the trailing cab must be turned on. It doesn't matter what position it just has to be on.
