I needed to reset the CVs on a F series loco equipped with a Soundtraxx LC decoder.  Before I had the lighting direction matched to loco direction even though I had reversed the normal loco direction in the settings. Now I cannot see how to get that back....the loco needs to have direction reversed and I need, therefore to reverse the lighting function....yet cannot see in the manual how to do this easily.....only a CV that matched lighting to loco direction. So that I don't have to pull the shell off and rewire the motor leads, can anyone tell me a CV for this decoder to reverse the lighting control.....it should be possible because that is the intent of offering a CV to change direction....that the light could be changed also. Just too old to remember what I had done before. Thanks.
