Hi guys,
I'm trying to determine how to fiddle with the lighting on a pair of HO Proto SD-7's that I want to install decoders in. What I’d like to achieve is to have the number boards lit all the time using the factory bulbs and then adding additional lights, (both my SD-7’s are SP) to be powered and controlled by the decoder. My decoder is a Digitrax DH-121 with the NMRA plug. I am aware that a 330 ohm resistor needs to be added to the stock board in order to use the factory bulbs. I'm thinking if I leave the factory bulbs hooked to the stock light board and use them for the numberboards then wire the additional lights to the decoder this will give me the effect I'm looking for. Any advice?
