    I was wondering is anyone can assistme in building a circuit that would take the voltage from 3 LED's and have it drive 8 RGB single LEDS as extended lighting.

    This origional RGB Lighting is from a Gauge Cluster background lighting that use 3 LEDs (Reb, Blue, Green) to make 127 different colors. I want to extend the colors to additional RGB LED's in the Car as Ambient Lighting.

    I was able to tap into the Dash LEDs and drive one RGB LED external but one set of the dash LEDs dim a bit.

    A view of the LEDs in the cluster

    Here is a schematic I am working on
    I am not sure how the existing Dash LEDs are Driven, but I am assuming it's a chip on the cluster.

    I am going to test this soon but was hoping someone can look it over before I try to hook this in to my 600.00 Gauge Cluster on my Car....


    Here is a video of the Dash Lights and the RGB LED on the Left side
