Ideas to address truck tail light reflection from camper?

I assume from under wings of camper. Recently redid ours, Mostly to kill reflected glare of tail/brake lights.




I use Henrys sealer/damproofer #107 water/asphalt emulsion. Dries hard & textured flat black (rolled).
But Duplicolors flat black truck bed spray paint from auto parts works well, It has a very fine texture. Or any flat black paint.

Our third brake light/bed light is tied to interior light, I put switches on it. It was worse the reflected tail lights. Pulling those bulbs got old.
