anyone every think of just using silicone to fill in the gaps around the head light?

That's what I'm going to do. Just bought a tube of black silicone today. A little painters tape to keep it where I want it, I'll be all sealed up and it won't even show.

that black silicone will turn either grey or brown (depending on manufacturer) in a very short time.
Ive done the lower gap on all my vehicles for the past several years. although I did leave the upper gap for ventilation, as mentioned before, the headlamps can get pretty darn hot and I didnt want to tempt fate

I tried sealing my headlamps on my old ranger but nothing lasted very long, so I ended up just buying some covers. they did a pretty good job of covering the gaps around most edges, but also covered that gap between the headlamp and turn signal.

the stock image shows how much gap there is around the entire thing, but there is a significant gap also between the components that make up the HL assembly. which you can see a little better in the pic of the covers installed.
not sure how much of an aero effect it had, but Im thinking it had to have some.

d0sitmatr is right. The black RTV I buy is grey coming out of the tube! I may have to do something similar to what you did (maybe w/foam tape or corroplast), as there's a 1/2inch gap from my headlights to the bumper cover...

The foam tape didn't last either. By the next season it was also grey & weathered, and some of the adhesive was gone too, and it was out of place.

Silicone or equivalent is probably best.

I did this with black silicone on my black car. Can't tell it's there.

I used black RTV on my last pickup and after 11 years it was still black (once I washed the dirt off of it). The RTV I used on the topper for my present truck is still black after a little more than a year. The stuff I use is what Home Depot typically sells. I think it is made by GE.
