I am going to do the LED in the headlight mod. I am thinking of running 2 5mm blue LED's in each headlamp. If I run all 4 in series, is it correct that I do not need a resistor? The LED's are the ones from http://www.lsdiodes.com/.

With 4 of those LEDs in series they can handle up to 18 volts max so you are safe with that. And no resistor needed.

That's what I thought, thanks.
