It seems like you have done some great modifications to the John Deere 6R Extra Large Frame Edit! Having three different beacon bars to choose from is fantastic, even though only two of them are currently functional. It's always nice to have options for customization.
Adding extra lights to the cabin is a thoughtful touch, especially with the inclusion of Big energy-plow lights and Ozz lights. It's unfortunate that the Ozz lights are a bit glitchy with the high beam turning on when the parking lights are activated. As you mentioned, this issue can likely be resolved by adjusting the XML file associated with the lights.
Moreover, equipping work lights on the front loader bar is a practical addition that can enhance visibility during nighttime operations or in low-light conditions. Overall, it sounds like you've put a lot of effort into expanding the functionality and aesthetics of this tractor mod. Keep up the good work!
