Question:
I have 12 vdc on the brown line without the lights connected. as soon as i connect the wires, it s to 7 vdc and its not enough to light the LED. Why is it dropping voltage?

It sounds like the ground connection often in the mounting hardware of your lights is not connected well. This ground needs to be bare metal to metal and free of all corrosion and debris. If with a clean ground you still are not getting the desired function, you will need to add more resistance to the light fixture by adding a load resistor like the LED Light Bulb Load-Resistor Kit # DI34ZR to draw the desired power for proper function.
