I don't know if there is any rule from first but the OI user guide specifically says not to power LEDs off of the joystick ports because current and voltage draw will throw off joystick readings.


"Do not use +5V Aux for lamps or LEDs, excess current will affect joystick readings.
The current limit of the +5V Aux from all 4 ports is about 100mA. The Aux Fault Led will start
illumination when the current draw from the +5V Aux Outputs total about 120 mA and the +5V
Aux voltage will have dropped to about 4.5 volts. Worse case, short condition: after about 30
seconds, the voltage will be at about 300 mV with a current of about 250 mA."


It actually says that once for each joystick port.
