Thanks for the info. The light does in fact work when in reverse...just user error on my part:) Since this is my first attempt at DCC and sound I'd rather stay on the lower side of the sound decoder range. I don't think I'll use all the features of the soundtraxx heavy steam...is there another alternative?

Thanks

Jeff

greetings - I'm new to dcc so this might be obvious, but how do I control the backup light from my power cab? motion and front light work. do I have to program the power cab to use the b/u light? Also, can you tell me which sound decoder would work (USRA Light 2-10-2)? Is it simpler to replace the factory decoder? Thanks - Jeff
