i have previosly played around with a couple of LEDs from radio shack and the bulbs are 3.7volts min and 4.5 volts max and i did the equation that Illusion had on his website:thumbup:, and he recomended 470-Ohm resistors and i got the ½ watt ones and used them and they came out fine
i went to radio shack yesterday and i saw that they had 470-Ohm ¼ watt ones so i picked up both

so my question is do i use the ¼ watt ones or the ½ watt ones

Thank you,

here is a picture, it's hard to read so i drew on the pic


i want to do this the correct way, and not mess up my car so i apreciate any input
