The mcd is just the brightness - doesn't affect the circuit. Now, with
that said, you will have a new circuit based on the voltage and
current draw from the new leds which means a new resistor to make sure
you don't fry the leds. Also, if it is on an AC circuit, the diode or
bridge rectifier may have to be re-worked.
Does anybody know what the original voltage and current draw is for
the stock LEDs? The ones I am considering are 1.8-2.2v /24 mA.
Will this require new resistors on the plane board?
Thanks again,
