Twice this past week, early in the morning, as I was driving down the road, my headlights went through a "dimming" cycle for almost 3 minutes. They behaved as though they were turn signal blinkers, dimming a bit, then returning to full brightness. The only "odd" occurance was that my stereo red-light button was blinking quickly the last time (everything else was normal). I called my local Volvo dealer to ask about this and he said that was a new one on him, to bring it in when the problem reoccured. Since I live over 60 miles from the dealer, I would prefer some advice from this board before doing that. Any advice??? THanks. Rick
