it gives more options to make the parts match. I wanted this so I can pick which color looks best. You never can be too sure how good the colors will come out w/ these things. Also w/ the 6 color inverter I only have to use 1 inverter to run all the gauges, the HVAC and the HL ( via the 2 y-splitters the lady is throwing in for me). they will all be color controlled simultanueously aka all 3 pieces will change at the same time and match perfectly.
