Welcome to EM!
When you are driving, can you "see" where the top edge of your headlight meets the front of your hood? If yes, then maybe you could do a tuft test. Cover one headlight with masking tape, tight so it won't "wobble" in the wind. Then tape yarn tufts right behind the headlights and maybe for a few "rows" of tufts back. With one headlight covered, you should be able to watch the tufts and compare the benefit.
Does that make sense?
