I figured I'd post this here so hopefully I won't get a bunch of dumbass replies. I'm trying to put LED turn signal lights in the mirrors of my car (I don't want opinions on this, I've already made the decision), and I'm putting 7 in each mirror. I know I need resistors so the 12v from my car doesn't explode them or set my car on fire or something. I bought 20 6000mcd LEDs and he included 20 1/4 watt 470ohm resistors. I asked him if I could run all 7 LEDs of one resistor for each side and he said only to run max 3 per resistor. Is this really true or should I use one resistor for each LED or can I use one resistor for all 7? I want to make this safe so if I have to run one per LED I'll find somewhere to stick the damn things. Thanks for any help.
