Easy one Ted. Green LED's require more voltage than red LED's to light. If you wire them in parallel, the red will light and starve the green ones.
The correct way to do that is wire each string separately.

I assume that what you're saying, Gunrunnerjohn, helps explain the dilemma Bill noted below in a forum post about his MTH Holiday LED-equipped boxcar.

I just put car 30-7094A on the track to test along with a post war steamer powered by a Lionel CW-80. The lights were fine for a couple of minutes, then glowed brighter for a second. The blue and green LED lights stopped working, but the red and yellow lights are continueto work.
