Are you saying they got rid of the seperate light board for the ditch lights, that allowed independent control of said ditch lights ? If so, personally I'd say that's a step backwards
They did, it is now a pair of light tubes straight to the decoder. The decoder now has ditch lights coming straight from the decoder.
For me personally, this was a major pain, as I wanted to convert some pre-existing units over to sound. I had to completely take out the existing light tubes and redo the whole front end. I am glad I only had three to do (I pre-ordered 3 of the sound equipped units), I was debating a fourth, but after seeing how difficult it was I decided the fourth was not worth it and sold it off.
