I agree with the fuse thing. I had one light go out on me and I thought it was a bulb or worse, the electronics. turned out to be a fuse. Diddnt appreciate that the GT has seperate fuses for left and right headlights. Never owned a car with this set up before and assumed that if a fuse was to blame, both lights would go out.
