This is the most popular trend I've seen for the 2013+ tail lights, starting back in 2013, before modding the oem tails was normal. We started cutting into these, and figuring out how to remove the internals, not break anything, and then refinish and reinstall everything to look like it belonged that way from the factory. To this day its still super cool to see these tails modded on a Genesis Coupe!
*Heads up, this is the cost of modification only, not including the cost of new tail lights.
We start by cutting open the tails, removing the chrome internals, and popping off all lenses, trim, and circuit boards. Then we shoot the parts in satin black, reassemble with the factory LEDs, and then get the housings back together for a polished finish that completely transforms the backend of the car.
