Hello all

I am newish to the DCC world. I am happy with the basic CV functions and settings.

I want to be able to reduce the brightness of the head and tail lights and also the internal lighting of my class 121.

I use the bachmann dynamis system and have down loaded the decoder CV listing but I don't fully understand or really know what I'm doing to reduce brightness CV. I don't want to chance it and mess up the decoder.

I would be grateful if some one could detail me a step by step guide to adjusting which CVs for each individual lighting function.

Thanks in advance

Will
