Hi, we do a back light conversion of E53/E39/E38 cluster and here is a few colors available (white, blue, green and red) to turn cluster' backlighting to an amazing look. I did a video to show the difference between white and blue LEDs. The information display color can be changed as well. Comments are welcome!
