Hey tetters. Go to the soundtraxx website .Go to the manuels and it tells you what you need to know.Upon setting up your decoder yopu have to tell it you are using LEDs by setting the CVs after install .They recomend using a 680 ohm resistor in each function leed for LEDs.After your done and before you button it all up test it and set the lighting effect CV to LED use.I have used NCE decoders in the past and they are the same way "Sometimes". Try that and I hope it works out .Page 31 of the tech manuel will tell you about the CVs and 25-26 of the install manuel will show you the LED install .I find with these dont let them get you down.I have done lots of these and I found alot more of my time was spent reading manuels to understand why than the install took. Goodluck.MartyG
