I once converted the Case Optum from LS19 here.
– Bug fixes Zugmaul Attacher!
– License plate including lighting installed
– Color choice installed
– Rim color choice installed
– Wheels selection expanded
– Tinted window
– Tachometer numbers made darker (unfortunately more is not possible, should it still not be easy to see for you, there is a zoom mod for the cockpit!)
– 8 selectable all-round lights including RulBars
