Do you know how to read a wiring diagram and diagnose a wiring issue. If you do then pick up a chiltons and work through the wiring. If you don't then I can't provide you much info outside of that. I don't know off hand how these are wired. I'm thinking there is a possibility it may be a headlight switch. I don't have a diagram to see whether it could be or not.

if its the running/parking lights that arnt working check for power at lights when u have them on, if no power go to the fuse block and find the fuse for running lights or parking lights maybe blown fuse or something
