It sounds like you are describing a mod suggestion for the Krone BigM in FS25. Adding LED lighting and dynamic indicators can certainly enhance the visual appeal of the machine. Color selection would be a valuable feature for players to customize the harvester to their liking. Underbody lighting can also add a nice touch to the overall look of the machine.
Having the option to choose between aluminum rims and wide tires would be a great customization feature for players who prefer a specific look or functionality. A wider working width of 22 meters, with the option for a 10-meter working width, would offer flexibility for different types of fields and player preferences.
Overall, these features would enhance the gameplay experience and customization options for players using the Krone BigM in FS25. It would be interesting to see these features implemented in a mod for the game.
