I moved my Hella 500 driving lights from my safari bar to my bumper. When I first disconnected the lights, I first removed the fuse. I took the lamps off the bar, disconnected the power and ground wires to each lamp, moved the wires up through the grill, mounted the lights to the bumper, and connected the wires to the lamps. When disconnecting the wires, I kept the positive and negative wires to the left lamp separate from the right lamp to make sure I rewired them correctly, which I have triple checked. I reinstalled the fuse. When I turn the key over and hit the switch, the lights come on for a second, and then the fuse blows. What can be the problem? The only wires that were removed during relocation were the two wires connected to each lamp.
