I want to add an interior light and side markers to my wooden caboose. I plan on adding eight wheel pick up and using 820 ohm resistors to all lights. Does this sound right? I also would like to install a decoder to independently operate the lights. Any suggestions on what decoder to use and can that decoder have its own address which will be recognized by a DCC system? I don't want to use a battery and toggle switch to power the lights. I want to use DCC control. It's my new addiction! Thanks for any suggestions and thoughts on the matter.
