Headlamp Hell. The driver's side headlamp goes out intermittently. It happened this morning, fortunately it was breaking light. when I got to work and looked at the lights, they were both out. I'm hearing it's a common problem. I have a 2008 Prius. How do I know whether I have a HID lamp, or a Halogen? My owner's manual lists both kinds. I'm taking the car to the Toyota dealer tomorrow to have him diagnose the problem.
