It shows the cool white leds in a stock cluster and a couple of other colors. Warm leds will look like it has original incandescent bulbs just brighter. Cool leds make the numbers look nice and white(my preference). Colors look ok if your trying to match a custom paint/interior. Some of my lights quit working a little while after I installed them so I cleaned up my connections and installed some bulb grease (dielectric) on the contacts, problem solved.
