I was looking for a similar channeled effect for my taillights. I ended up plopping down $65 for some AVS products from Moss Mustang. I painted them bumper trim black and put them on the car. I also added a magnetic black out panel from Latemodel Restoration Supply to the center. The car looks great, and if I decide that I don't like the look, I don't have to figure out how to remove any pain from all of the stock parts.
