Ordered some M4 CS OLED-style tail lights for the car. Don't have them yet, but they are similar in style to the second set of lights in the linked video below. I was sent a video of the welcome sequence, sequential turn signal, brake light, and reverse light in action by the manufacturer and, fingers crossed, everything looks flawless so far. Will definitely post pics once I have them and put them on the car
