I had purchased a handful of each color, and then desoldered one red from each bank and replaced the red with the orange, or replaced the red with a blue. This was the easiest way, and simple to do. The red board with 3 LEDs on it was the base from which I started.
GCMRacing GCMRacing did sell a light kit at our Canadian web store when we stocked this roof, but we no longer do this kit. There are some matching items linked below, and can be assembled in any configuration you wish. They will fit into the light pods directly. Other colored strips are also available from the same vendor.
