Hi, I'm trying to lower a 12V DC voltage source to around 3-4.5 volts (tapping power from my car's cigarette lighter to light up some LEDs), but i have very little to no technical knowledge of electronics whatsover (i know the very basic BASICS), but i can solder and stuff okay.
My friends say i can hookup a few resistors in parallel to do it, but i dunno what resistances i need to get.
Is there a formula or something?
Thanks
