Model Railroading > BLI C&O 4-8-4 How do I wire in a new headlight?

I have a BLI brass hybrid C&O 614 that I received second hand.  Apparently at some point the smoke unit fried killing not only the smoke unit itself but also the headlight LED singed some wiring.  I'm not sure I'm ready to attempt a full decoder conversion yet as the engine runs and sounds great.  I really don't care much about the smoke unit.  That really leaves the headlight as the only thing I'd like to fix.  Does anyone know which wires I would wire a new LED to? Would a resistor be needed or does BLI incorporate resistors into their decoder?

Is this a bulb replacement?  or ?,, If your a amatuer and this is your first I would check around maybe call  the maker,  they're a little more complicated than a Athearn diesel IMHO, and like they say YRMV, Good luck
