hey Bach Mann  need your help

Have built a Logging speeder cab using a DCC eqwipped side rod  Davenport, Bachmann of course! Have switched the units nose for tail, the cab is facing rearward now. Of course the directional eqwipped headlight only works when going backwards, everythiong was going great then I hit the rocket science wall, long story short I am sitting here with a cab that has a burnt out bulb from trying to wire it directly to track voltage, wouldnt mind having a non directional headlight but that brings us back to original qwestion, does this side rod have a way to run directional lighting in both directions? ditto for all bachmann DCC Locos?
any help will be appreciated
thank you kindly
KC
