Hi
I'm trying to install a set of lights in my 2008 f150. The directions say to hook the white wires to the positive wire of the driving light. First which is considered the driving light and then which is the positive wire?
thanks

 

The "halo" could be triggered by any light you want. Make them flash as turn signals if you want. Most people have them turn on with the parking lamps. Use the side marker light. You could wire them into the ignition if you want, so that they turn on as daylight driving lamps whenever you turn the car on.
