I have one of these Lighted Rear Applique's. I was one of the first people to install it on an S. I put it on my '13 then moved it to my '17. Its really one of the two coolest mods that I have done to my Tesla. I get all kinds of looks when sitting at a traffic light waiting to turn left or right. You can see the people behind smiling and pointing at the back of my liftgate. The way it scrolls left to right and right to left is amazing. I am in the process of upgrading to the GEN IV now.
Guys, hang on to your OEM applique. If you later sell your car or trade it back in, remove the lighted applique, clip the wires and tape the ends and put the Lighted Applique on your next Tesla or offer it to someone on TMC. You will get most of your money back. I got the MC Red one and it blends so well with my Red car, you can't tell any difference.
