The LEDs being produced today for illumination do not require any resistor.

They may have a resistor packaged with it, but a LED is a *DIODE*, and
it requires a resistor.


Well, yes that is true. However they do not require an external

is needed in built into the unit itself.


I considered that. "Built-in" is not equivalent to "nonexistent".
