Hey guys, I'm wiring some LEDs into my car, I bought 14 and now have 4 that aren't burned out, you can see I've had some trouble.
On a 9V circuit everything works dandy, 12V no.
Okay, so I've wired 3 LEDs rated at 2.5V Max 20mA, Put a 9V to it and they lit up nicely. Now I used a resistor calculator that told me to use a 220Ohm resistor.
I put the resistor on, in this order.
Resistor (Red to Gold) LED1 LED2 LED3
Nothing happened.
Resistor (Gold to Red) LED1 LED2 LED3
Nothing happened again.
Why is this happening? I'm running thru the lighter and it's definately live, but my LEDs won't light up unless I take the resistor off, and then KABOOM.

might be 5V+ LEDs , you might wanna look into that

Well I ordered em from LSDiodes.

Okay, figured it out.
If you wiring up LEDs make sure you remember resistor coding
I was using a 220000 ohm resistor, I've switched to 220 and it works
NEW PROBLEM
My resistor is getting really hot, is there a way to stop this?

ACK
Red Red Black is so close to Red Red Brown :S
I guess using a 22ohm resistor where I need a 220 will cause the overheating, huh?
