i saw a topic on here about running 3 volt LED's in your car...to do this you need to have a resistor, but which one? Its' a 330 ohm resistor...heres how you calculate that if anyone wants to know how :

Just thought that might help some folks out. Also I have a question. if i have a power wire, connect a resistor to it, and then a wire out of the resistor, can I split the wire coming out and run multiple LED's off of one resistor? Iam planning to do an LED light conversion throughout my car and though that might be a factor to know about. I'll post some pics later to show my progress. any help would be greatly appriciated!

Thanks,

-Nick

No you cant because you are those leds are all pulling a certain amount of power so you have to calculate the amount of leds you are going to run with the amount of power you have. This is the calculator you need to use you can calculate as many leds as you want in one series. https://www.metku.net/index.html?sect=view&n=1&path=mods/ledcalc/index_eng
