The front projector headlamps do not put out enough light to safely drive on unlit roads at highway speeds. There is also little light projected to the side making turns unlit. I recently had a near hit with a pedestrian on an unlit street because of no side lighting when making a slow turn. There are no higher lumen replacement bulbs available.
