Headlight relay is bad. Its in the fuse box under hood, not sure exactly where. I heard its relay number 43 or 45 or 46 and I don have a book on it but it is the headlight relay you may can turn the ignition switch to on but not start engine up and turn headlights on and disconnect the relay under hood fuse panel and when the lights turn off from disconnecting its relay that is the one you replace. It will look something like the one below (photo)
