Ok for parts I used 2 diodes per side, Radio Shack carries them and the ones I got are 12v. I threw out the package so I don't have a number, but I'll be stopping back in someday soon to get more.
Then the resistors are all a matter of preforance, but I used a 220 I believe. I actuall y but 3 resistor sets going from lowest around 200 something up to 1000 just to be sure. You'll only need 2 but the come in a package of 6.
Then the lights, well I ended up getting them from my brother-in-law bought found a link for the same ones, at
www.superbrightleds.com . They have a good selection of parts. Only problem is the strips are too short IMO and I will be doing up a circuit board with the pentastar design on it instead, so stay tuned.
In the end you need:
4 diodes 12v or higher
2 resistors, prefer the ones in the 200 range
strip lights or whatever else you use for LED lights
2 bulbs to use to connect to your exsisting socket
Now the Diodes only allow current in one direction, the stripe ends goes away from the incoming current. Resistors can be soldered either way. Also LED (light emitting DIODES) will only light if the current is going the right way also. The strip lights are an easy way into doing it, but not the best. A PCB board is ideal and their are websites about making your own circuit board using copper, transparency paper, a laser printer or photocopier (must use a toner based ink) some acetone and that's about it. Then you just design the circuits, solder on the components and viola!
So I've ditched these strips and will be doing a Pentastar design, I think that will be the cat's meow.
