I'm not a lights guy I presume...It's like virtual backglass, it's not something particularly interesting for my own taste. I'm more concerned about controls, forcefeedback, sound, that kind of things.
Of course if I buy a ledwiz or other interface with hundreds of outputs, I'll add some lights...Just because since I'd pay for these options, I'll use it. But if someone create a light version of ledwiz, with maybe 16output, with a significantly cheaper price, I'll be the happiest man.
