I have this image showing how to do it with one. Mind you, I am not too keen with my electronics so that is why I am asking for help with it because I don't want to mess it up. This would be going into a car actually so if that changes anything then there ya go. I'd appreciate any help...especially from twistedsymphony because I have seen that he is one of the electronically advanced fellows on the board. Thanks guys

Oh, and the circuit is going to be a part of this car...

What exactly is your question....? It seems like you've got everything you need. Just use the 12v source in the car and change the resistance values in order to use multiple leds. Also, you can't hotlink to those imagestation photos. <

if you want TwistedSymphony to look at it you may want to try posting it on www.hardmods.net forums... seeing as how he is an admin there Im sure he would love to see it.

Yes, there's even a special schematics forum. <

Argh I didn't mean to answer my own question. I guess what I need help with is changing the resistance values. <

the 2N3904 will act as a "voltage-follower" for this application, so max Voltage your gonna get is around 5V or so across the LED/resistor coming out of the 1458. It'll actually be a bit less, but dont worry about that.

Use your specs for your LED's and 5V for your voltage source to figure out the resistance you need. If you dont know how theres a nice pinned topic at the top of this forum.

Edit: wrote "switch" first but wasn't too appropriate description.

OK thank you very much. That really helped. And thanks for the car comment too...it's a dream
