3 colours and 1 running LED

Hi,
I’m seeking a solution to my mini project. I’ve designed the Brazilian F1 track and 3D printed to be put on a stand. A ledstrip illustrates the racetrack.
I want to divide the ledstrip in 3 segments in 3 different solid colours that illustrates the F1 sectors with each 25 leds. The problem, how do I get 1 (white)led to Chase (illustrates a F1 car)? So far I’ve managed to get 1 chasing led in each segment, but I only want 1 chasing across the entire strip :slight_smile: your help is highly appreciated.
