Hello, I want to exchange those white LEDs in a Lupine Cluster into red ones. Is that possible without changing the resistors ? I think if I'm only changing the LEDs I'll kill those red ones because of the voltage
Is my thinking right ??? /ubbthreads/images/graemlins/help.gif

I'm not familiar with the way the Lupine Cluster manages the power to the LEDs, but you are right that if it uses a simple fixed-value resistor to limit the current to the LED, then you will blow the LEDs. Reds run at a nominal 2V, while whites run at a nominal 3.6V.
