listen you can go to like radio shack or where ever you are getting the leds and this is what you got to get as well. you just need resistors that will drop the voltage from 12-14 to 3-5 cause an led rated at 3.7 can handel a little more. but no the more power will not make it light up more. the resistor value is 220ohm .5 tollerance. a resistor must be added to each led so the amout of leds you are buying you need resistors no prob though a pack of like five resistors is 99 cents., this is the value that will work for you i have done just this. on my car and my led are fine .
