Many modern diesels (Dash 9's in particular) have safety of porch lights on the walkways and stairwells. I was hoping to model the effect by having the porch lights (I was thinking 8 leds in series on one aux) come on automatically when the speed dropped to a certain level much like the tsunami automatic bell does. Does anyone know how to set automatic lighting events in DCC? I am currently running a loksound Select on a MRC Prodigy Advanced Squared but I could move to a different decoder and put the Loksound in my heritage P40DC. Thanks in advance
What about Using Fibre Optics
QSIs decoder might be best for you. They do have functions that come on automatically when moving or stopped and change whether from reverse/forward.
I have used light pipes as well as fiber optics to move light into different areas.
