What do I need to wire LED's up to be powered by 12volts. Say I want 5 or so LED's in my car to come on when a switch is pushed.

you should use a relay to power up all of those LED's

connection of relay: pin 86 12VDC

pin 85 ground (switch should be installed here)

pin 30 12VDC (fused of course!)

pin 87 going to LED's

pin 87a not used

hope this answers your question.

Yes and no. Can I wire LEDs in without resistors or do I need special components.

you need resistors if they are 3 volt or less around 500 ohm

You don't need a relay all you need is a resistor for each led.Contact ssullivan777 here on this forum he can help you out.

If you are running +12V then I would recommend that you use 12V leds.

you dont have to use 12V LED's they are expensive. I would just get a 2-3v LED and a 500-600 ohm resistor and hook it up to 12V Cheaper

I'm wiring them under my dash for lighting instead of neons. So how many can I connect in series, I've read that you can connect like 4 3volt and not need any resistors, is this true?

try this website http://linear1.org/ckts/led.php they have a resistor calculator to find out what size resistor to use
