It's best to add a resistor in series with the string to limit the current. With many LEDS in parallel without a resistor it's pretty much guaranteed that you will over-stress the pin and destroy the Microcontroller. On the other hand, adding a resistor will make the LEDs disappointingly dim. The answer is to use a Relay or Transistor to drive the string.
