    Looks nice. Did you use plug and play LEDs for the 2nd row reading lights or did you make boards for them?

    The dome lights are 10 LEDS hard wired together. The map lights are fitted with WLED-xHP6 SMTs. I ordered them from http://www.superbrightleds.com. They put out about 35 lumins each.

    By the way, it is a better idea to say the starting voltage is 14.5V instead of 12V. This is why a lot of cheaper LED lights go bad. THey spec them to 12V to save money, but car charging systems fluctuate between 12V and 14.5V.

    Where did you wire in the lights that light up where your feet would be? I've been thinking about that for some time but I'm deathly afraid of creating an electrical "gremlin"

    I agree completely, I am planning on putting in a voltage regulator for the power that goes to my cluster, just to prevent the LEDs from being over driven.

    Thank you sir, But did you just wire them up independently or are they into the dome circuit? That's how I'd like to wire up mine so they come on when the doors open and etc.

    Then may I recommend the Sharp PQ12RD21 Low Drop out voltage regulator. It will regulate a constant 12V needing only .5V of overhead, unlike some that need 1.5V-3V of overhead.

    Alright, Went to tackle this one today, but stopped once I got the Lights off.

    Where do I wire it into?

    I made a plug from an old 194 LED and plugged it into the factory socket

    And $15 Later I have a 194 LED Replacment Bulb. Ripped it apart, and now Im confused

    So thers the two leads that lead out of the light? Are they both Anodes? Or is one the Cathode? How Do I wire the Anodes and Cathodes into the holder?

    They are just a positive and negative leads, however all you need to do is strip and slide wires into the holes and bend them around, to make contacts. You don't need to worry about polarity, because you can just rotate the plug 180 degrees in the socket.

    So I wired up mine yesterday for my middle dome light and they worked for a bit(tight fitting because i used balsa wood as a base, Then I hit a bump and 1 of the lights blew up basically. So Im not sure if the resistor got knocked off, or what, but I want to redo them.

    Ive had this project board for the longest time and its the only kind I can find around my house. It has copper plates on it to direct current, How could I use this for the dome light?
    Would putting all the positives on the bottom(copper side) work? and leave all the negatives on the top of it?

    there are tons of posts on this site about leds and how to use the copper plated project board
    http://www.instructables.com/
    there is also alot of other really good info, hope that helps

    Ok, I need some help here with a problem I am having with a flikering LED. When cold it works fine, after its been on for about two minutes or so, it starts to flicker for a while then just goes out until it cools down again. Anyone have any suggestions?

    It's dying. Plain and simple as it is heating up its making it worse.

    One thing I just noticed, no way in hell those things put out 35 Lumens at a 31mA current draw. Some of the BEST (AND EXPENSIVE) LEDs right now put out 20ish Lumens at 50mA (this excludes some of the super high power ones which can get some crazy efficiencies but at much higher currents).
