I got all warm and fuzzy reading Brian's post.
I can tell , without a doubt that Mr Martin has reached that point in his life where he is fully secure in his manhood.
How else could a guy fill half a post with pictures of hearts and smiley faces kissing.
I like these;
I know the truck guys are doing them to death, but I think a set of those, mounted vertically, and aligned with the vertical belt ,(with a 1" space) would look good. I would think the curve could be so similar that it would look right at home on your car. Maybe recessed and turned upside down would work.
I love mustangs, but like Brian said, the mustang tail light craze was over several decades ago.
Just my opinion.
