As we are driving the lights and anything Electric goes wild and blinks to. It sucks alot becuase when it rains it makes it hard to see. they honestly honda needs to realize they need to fix this problem becuase one day someone is going to be killed by this. I love my car but this is a dislike turnoff to much cost in it to fixing it. voltage goes high and low.
extremely low headlights.
