Normal for DC: White lamps and ditch lights in forward; red lamps and ditch lights in reverse. On DCC the "Dummy" unit no longer recognizes the directional changes ( it does not have a decoder ).

HO / Re: interior lighting and dcc - Acela

I found this thread helpful (in combination with a couple calls to Bachmann USA (215)-533-1600) and thought a summation might help:
The current ACELA kit is a DCC "A" (powered) Unit and a dumb "B" (non-powered) Unit with three cars: Club, Business and First Class.
When run with the "out of the box" DC Controller ALL lights respond to throttle input as do both the "A" and "B" Unit Head and Ditch lights. "A" and "B" Head lights also change from white to red according to direction of travel. All this is due to the voltage/current on the rail and the polarity of the rails.
On a DCC track the behavior is: The "A" Unit is the only piece where the lights will recognize the DCC "Function 10" and reverse of direction. Club, Business and First Class cars interior lights will ALWAYS be on as the track is always "hot". "B" Unit Head and Ditch lights will NEVER come on as they are not connected to ANY DCC module (and therefore know nothing about "Function 10").
On any DCC layout I'd think cutting power at the wall outlet (or the equivalent) when not in use would be advisable or else the rails will stay "hot" pushing up the electric bill and presenting the potential for inadvertent cross-rail shorts.
