Good question. Look in the cup holder towards the bottom and see if there is a semiclear ring going all the way around. It's probably no more than 1/8" thick. If your cup holder looks all black inside, the lighting ring is not there. Idk if the lighting is a separate option from the premium option. I thought it was included as well.After reading your post I realized my new 16 GT Prem Pkg cup holders do not light up. Is their a package To make those work. I assumed that came with the car, am I wrong? Should I have the dealer see why they are not working?
