The headlights are in a very favorable pressure gradient regime,with air attacking all around the lights location.And with enough surrounding radii,and stagnant air pooling inside the headlight bucket,the surrounding free flow should just glance off the area without separation.
I suspect that the air is already displacing into streamlines well in advance of the nose anyway.
Most wind tunnel photos reveal this Prandtl line of discontinuity as the air attempts to avoid sharp accelerations.
