Follow-up info
The old lights were Command Elec. #300-30 and the new are the Bargman 5 function lights.
The parking brake lights work but again stop the turn signal from activating. Since the Bargman fixture brings the three ground wires (white) together and provides a single white for connecting to ground and the old fixture had three white ground wires, I've tried various combinations of the existing ground wires connected to the single ground provided on the new fixture but it seem to make any difference in functionality.
I'm lost here. Hate to use it without turn signals when I lose them as soon as the dash light switch activation cuts them out.
