Hello,
I showed You here the installation of a buffer capacitor circuit for the Trix V 80. I wrote there that there is a free and unused AUX port. This AUX port is mapped to F1. I use it in the following report for the cab lightning.

It is very easy to disassemble the case. I drilled a small hole into the exhaust pipe of the interior furnishing. It will be used for the small cables for the LED:



I use a universal LED-board, ready equipped with resistor and diode. The small board can be bonded to the ceiling of the drivers cab:



Finally, the case must be assembled and the cable soldered to the U+ and AUX port.



After activating F1 on the Mobile Station 2 (You just have to assign a symbol to the F1 button), You can switch on and switch off the light:
