Check out this led calculator:
LED series parallel array wizard
You should check your led specs for voltages/current, typical voltage is 3.3V, and current is 10-20mA
Seems that 10K resistor is resistive enough - more resistance, dimmer the LED. So minimum 1.2K
Source voltage 14
diode forward voltage 3.3
diode forward current (mA) 10
number of LEDs in your array 1
Solution 0: 1 x 1 array uses 1 LEDs exactly
+----|>|---/\/\/----+ R = 1200 ohms
The wizard says: In solution 0:
each 1200 ohm resistor dissipates 120 mW
the wizard thinks ¼W resistors are fine for your application
together, all resistors dissipate 120 mW
together, the diodes dissipate 33 mW
total power dissipated by the array is 153 mW
the array draws current of 10 mA from the source.
