It would be great if there was a way to adjust the brightness of the indicator lights in the driver's cab. (Brighter/darker) These are totally overexposed. And in the dark it's extremely blinding. You can only guess at the text of the indicator lights because you can't read them during the day or at night. After all, this function is also available at the PZB.
By the way, the yellow HS-Off indicator light doesn't work either. (the 2nd from the left) This should actually light up when the main switch is turned off.
