Gotta get wires correct
I would assume most of us that are installing these lights remove the switch from the wires so as to easier feed the wire loom through the firewall. When replacing the wires back to the switch, the white wire should go where the single line is, the blue wire should go with the circle is, and the red wire should go where the double line is on the switch. I was experiencing the exact same feedback as the majority of these reviews, and then I switched my red and blue wires, and it instantly worked as described.
