Exterior light on driver's side stopped working. I noticed when I pulled into my garage that the light was not working. The only way I could continue to drive the car is when I used the high beams. Now, as of last night (March 27, 2013), the driver's side high beam is not working at all. I have taken the car to the repair shop and told the lighting module needs to be replaced and that it would cost approximately $700 to fix. I need the lights to work, so I am having it repaired.
