    Mine quit a while ago and since the nice weather is on its way out i figured i might as well get to doin somethin about it. Has anyone rewired it to a couple of simple cheap lights instead of paying through the nose for thermoking's light. Seems pretty simple but simple doesn't always work. There is 3 wires coming from the plug on the unit. 1 has 14 volts while running, the other 2 nothing. I'm guessing the 14 v is for the all ok light. One of the others must be for the uh-o light and a ground. Does that sound right to anyone

    Have you made sure it's not simply a blown or missing fuse?

    Not sure which wire's go to what, but you can easily replace the original. Swift just replaces them with Marker lights. Usually one green and one red. next time Im near one of those I'll give the wiring a close look.

    Thats my plan as well. I figure a couple of those little bullet light would fit on the bracket the TK light is on now and cost $10 instead of the big money TK wants. Only gonna have this trailer till the end of the year anyway when the new one gets here. Thanks

    I just sold the trailer as it was. If you have no ground that could be your problem. Try starting it up and as it goes through its pre start it should send power to the not ok part of the light. Then you will know which one is the ground and start with that
