The " Blue dots" can be put in a set of lenses. Simply drill the correct size hole and install. I would check some old hotrod sites. Perhaps Speedway Automotive. I ran them on my Harley for years. You might also check to make sure they're legal where you're at.:bigthumbsup
You can't buy a set of ready-made lenses with them, they are illegal in most areas from what I've been told. They have to be added, but if your lense is curved then it's difficult or impossible. If you shifted them off center on the Mustang lense to where it's flatter they would look wierd.
I know someone with a '52 Chevy Deluxe that added them. They are illegal here in CT but he's rolling the dice that the police won't ticket him.
