Car Shaved Tail Lights

Shaved tail lights on a car is kind of unheard of but I want to attempt it. I found this image online and I’m dying to do the same thing. What did this person do in this position to get car shaved tail lights? Looks like he used a backer then fiberglass. Could I just use body filler to fill the entire area?
