Ok, I had a problem with my 2008 Toyota Prius. The driver side headlight stopped working. I tried replacing the bulb, and it still did not fix the problem. This year Prius had High Intensity Discharge (HID) Lights, which require a high voltage module to ignite the lights. In this video I show the trouble shooting and replacement of this module!
