S4 Diesel directional lighting

I have an HO S4 diesel.  It came programmed that both lights stay on regardless of the direction of the loco.  The light in the direction of movement is brighter than the opposite light (rule 17?).  I have tried everything I could find to change it to a directional light (light only on in the direction the loco is moving).  Some threads said CV 49 and 50 and some CV 33.  Nothing changed anything.  Is there a data sheet available showing the correct CV and what it should be set to to get desired lighting effects?

For directional lighting (on/off)

program
CV 33 = 1
CV 34 = 2
CV 49 = 129
CV 50 = 129

CV 30 is not relevant for lighting but make sure its value is 0 (the factory default value)
