Agree - 100 Ohms "ish" should work if you don't have a potentiometer to hand but Maplins is nearby.
Else try this equation....
Those are my principles...if you don't like them I have others.

Heh, yes that's how I worked vout the resistor value. Seriously though, a resistor won't be needed because if it was the LEDs would have popped long before.
