    Why are my brake lights not connected to my trailer?

    (Hard Wire Only) Vehicle has separate turn signal and brake lights, brake wire is not connected. Insufficient ground or short to ground on trailer or vehicle side. None of the trailer lights work for any functions. (Powered Converter Only) 12V power wire is not connected to vehicle battery.

    Is the brake light the same as the emergency light?

    On vehicles where the flashers are separate from the brake lights, this will not apply. The emergency flashers often use the same wiring, bulbs and sockets as the brakes. If all lights come on, when the emergency flashers are turned on, this shows the bulbs, wires and sockets are good.

    Why are the lights on my trailer not working?

    It can happen that if the main ground is not 100-percent solid, some but not all lights will function. This happens when the ground is not solid enough to pass the full required current for all lights, but only enough for some. Find the point where the trailer connector’s white ground wire attaches to the trailer frame.
