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?
