This is the full ambient lighting upgrade kit for Mercedes C-Class W205 / GLC X253 models 2015-2021. It transforms the regular 3-color lighting to 64 colors with the new AMG-style turbo air vents. Details according to the numbering in the picture: 1 - Front Turbo Air Vents (5 pieces): These are the core of the kit, the new turbo style found in 2020 and above models. They have internal LEDs that change color with the car's ambient lighting and are controlled from the screen. Comes with a control box and Plug & Play wiring harness without cutting. 2 - Rear Air Vents (2 connected pieces): Same concept as the front ones, but for the rear passengers, installed at the end of the center console. Comes with a connector and mounting adapters. 3 - Rotary 4D Tweeters with Lighting - Rotary Tweeter: These are the triangular ones that fit on the door corner near the mirror. When you start the car, they rotate and pop out on their own, with a lighting ring that changes with the system. It gives a very luxurious look and clearer sound than the original plastic ones. 4 - Burmester Style Speaker Grilles with Lighting (4 pieces): Grilles for the four door speakers, with a blue/colored lighting ring around the mesh, which works with the ambient lighting. Gives the look of original Burmester speakers. What does the full kit do? • Unlocks 64 colors instead of 3 colors • 100% compatible with the factory system, controlled from the COMAND / MBUX screen and steering wheel buttons.
