Pressure is what moves air aside. The advantage of having a high pressure area ahead of your head;lights, or car in general, is that it moves the air aside without any surface friction.
That's why a blunt nose is more aerodynamical than a sharp one, at least at speeds well below the speed of sound.
If the lamp units were in a smoothly curved area then covering them over would help, but the hood and side pannels fold sharply away so that does not matter here.
