Bi-polar LEDs

You may be able to get them at Radio Shack.
I buy here, but "standard shipping" is $6 -- so it pays to buy a bit. Things are really cheap there, generally, and the quality has been GREAT.

There are both 2 wire and 3 wire designs. The 3 wire types have a common cathode (or anode in some designs) and you can apply a voltage to 1 LED or both simultaneously.
The 2 wire types require you to reverse polarity to make them work. To blend colors requires AC current that alternately switches on one or the other fast enough that your eye can't see it.
Both types are available at AllElectronics.

I'm gonna give the door lock mod that Bob did a shot. With the electrical class I have taken and my brother who is studying electrical engineering and this board if I need any furthur help I think I can come up with something. I am gonna ask some teachers here at school of they can get me two of them.
For doing the door lock mod do you recommend using the two or 3 wire design?
Thanks for the quick response John.

Okay, now that I got a reaction...
Bipolar LED's are two LED's mounted in the same package. They are connected either back-to-back in reverse-parallel or with a common lead going to both of them, and then the other lead of each separate.
The generally are red and green, though other color combinations can be found. They allow a single LED to be driven to either produce red, green, or some shade of amber in between.
They are referred to as "bi-polar" or more correctly "bipolar" because the most common configuration lights up in different colors based on polarity. Really, the 3 lead kind are dual LED's, but not bipolar -- though they are usually still called that.

I've got one of these setups that is completely soldered and has wires running out of ,the project box and led's and holders all ready to go. The only problem is that my 98 has a little bit different wiring and I couldn't get it to work. If someone is interested in it, let me know. I am fairly new at soldering, but everything seems to work as needed when i tested it on the workbench. The wiring difference is something about on newer trucks the Theft light that is incorporated in this mod operates completely backwards than just a few years older in 98. This should work on any 01+ truck I would think..

Since the current limiting resistor is internal to the RAP module on the 98, it is only suitable for a single LED, not 3 in parallel. There is probably some way around this but it is not simple like the 2001+.

Yeah I agree. Thanks for all the help Bob. I am hoping that Radioshack will have the flashing red ones. That way I can do the install soon. Besides the LEDs and a few resistors I don't think I will need anything else since I am using flashing LEDs of only 1 color. Would you correct me if I am wrong. Also what type of mount did you buy to make it fit perfectly in that hole?

The LEDs above are the bipolar type. If you want to change to flashing red, you will need something like this:

In any case, the size you will need is T - 1 3/4 (also known as 5mm) to fit in the bezel which is a slightly loose fit in the lock pin hole - I ended up gluing mine with a dab of silicone seal.
