Umm this may not be about install ation in the car but i can find information on it anywhere and if anybody has a site r some knowledge of how to do this it would help. how do you hook up leds to you wall socket in your house??? From 120 volts a/c to 12 volts dc???

Ya iknow that site but iwant it ot be able to pluginto a 120 ac wall outlet sothey get power to light up this clock i have

use the calculator on there and plug in 120V, and you would need a diode to change the AC into DC

four LEDs with a voltage rating of atleast 3.5 volts, and some wire

get a 12v DC wall adapter. they will usually pull like 3 amps. the big black box thingies.

then get one of these DC powerjacks...

and then solder a small 16~20awg PAIR of wires to the +\- terminals to the 12v dc jack, and calculate the resistor for your LED. this wall adaptor will only pull .8amps. so an average LED will take about .02amps. you should have plent of power to run mutiple LEDs off this powersource.

this LED calculator should help you figure out the resistor for the LEDs so you can run the led off the 12v source.

http://www.lsdiodes.com is a great source for LEDs\wire\resistors, and they have some good tutorials on how to solder them where they should go.

i hope that clears up your question. but you will have to have an extra plug into the wall on top of that clock just to make the lights work.

if you got teh balls, you might check the ACadaptor for the clock, and see if it can support more current that the clock needs, and wire your leds right into your clocks powersource. thats what id do. but the ac adaptor will work for any mod you decide to do.

Humor me here...

3.5 volts ea, or total? And to wire them, would i just splice them directly into my remote lead wire in the headunit? Oh, and, since im running my speakres off the HU, (yeah yeah, poormans solution) would the leds take away any 'power' from them?

from this help got the leds up and working lookin sweet my 12 dollar coke clock

How many LED's max can i power off the remote lead...and would a few 5V Reverse Current bulbs work?

Install a relay... then you can hook them up to your hearts desire...

not to your hearts desire, just a few hundred
