This post has the sound of a college course question, and I would
recommend you figure it out for yourself.
hint: bear in mind that the speed of light is constant in a given
medium, regardless of the movement of the source, and that headlights
illuminate the surroundings via reflected light.
So here is another one: Given that light is not propagated through a
medium ("ether"), why is it not exempt from the Doppler effect?
