I have a new Baldwin 4-4-0 w/DCC& Sound. It runs perfectly out of the box on the default loco DCC address of 3. However when I program the loco to the new address of 122 the headlight will not function. Experimenting, I went back to the default address (3) and it works fine. I programmed the loco to an address of 22 and it also works fine (all sounds and headlight). I'm sure I'm missing something by going to a four digit address but WHAT? All the sounds work fine and the locomotive runs fine on 122, just no control of the headlight.
