Because people want the functionality of independently controlled lighting with different modes for day/night, yard, on trains, light engine, etc etc etc. basic lighting functions will not allow for that. We either have basic lighting as we always have with plug and play or we have custom set ups to allow for it, which is ultimately superior. We are currently working on our custom chips so that people can purchase them already set up to use to gain full functionality. People with lokprogrammers etc can already program their own to suit.
