LIghts on CIH 1660

Anyone familiar with the front work lights on this type of combine (1600 series, may be the same on 1400's I don't know)?

I have tested all lights by running power to them directly off a 12v power supply. They all work individually. I have an issue with the two left most lights (there are four mounted above the windshield). These two lights are loose and need to be tightened to the combine. The threaded stud on the light goes into the header above the windshield. I see no way to get to the back side of this to tighten the light down. The nut on the outside does not turn. This was a problem for the PO because he used a bungie to hold the two lights together. Can someone tell me how to get to the back side of this? I have the roof off and it is not in there. Any help appreciated.
 
We are having trouble with our two left lights also on our 1680. I switched some of the relays around inside the right access panel that's on the outside of the cab and they started working. Sure wish I could find a electrical diagram for a 1600 series. Can't help you on the tightening the lights up. Haven't had that apart yet.
