That is an issue with a lot of different lights from my experience. I was in that exact same boat and no offense CR I was cussing you left and right. Then it clicked. Anyways what ever lights you ever hook up and really any electrical connection remember that polarity does matter in most cases. if you have a digital volt meter it is easy to know which one is the "hot" wire. if you have a negative voltage on the display that your positive lead is on the ground.
