Ok, I am not having any luck, wired correctly.

Can the LED be tested outside the key?

 

David, you can test it out side the key pretty easy. Just stack the 2 batteries up and put one wire from the LED on the bottom, and the other on the top and hold them there. It should light right up.

 

Got it, cool much better than stock.

 

You know whats funny...i am soo glad to have an LED on my key, but its really only for finding my keyhole. I keep a 5-LED flashlight in my glove box. Anyone else have one of these? You can see the damn thing two miles away. Great for emergencies, or engine checking in the dark! It really makes it like daytime!

 

Thanx for this post. I'm gonna try it over the weekend. Got two 944's to do!

 

Blue S2,
Where did you pick up that led flashlight, I wouldn't mind getting one at a decent price. Thanks.

 

FYI, did the mod today on my key (all parts from Radio Shack), but for me, I had to put the LONG pole from the LED to the top of the batteries and the SHORT pole wrapped around the copper ground. It did not work the other way.

 

did mine with a left over green LED!!

 

I just did mine the ohter day. its amazing how much better it is. The feel to the button is a lot better also. before I did this, the light would sometimes not come on when I pushed the button. I have a blue and white LED (using white right now) and not sure which one I am going to stick with.

 

You had to switch the posts? Thats wierd. Oh well. At least it works!

Here is the LED flashlight i spoke of, - Inova x5 - do a search for it on ebay and theres plenty. Its a little pricey, but its worth every penny. Its indestructible, and element proof. I have one in each car. If your power every goes out in the house, you wont have to worry about light, this thing will turn a totally dark room into day! I love em! Its great for working on your car at night too! My friend and i installed his stereo equipment at night just using the dome light and this flashlight and had no problems at all.

 

Did mine the other night.
Works great!
Thanks for the detailed instructions with pictures.

 

I forgot to mention that I had to switch the posts too. Maybe I got the california emissions rated LED?

 

Just did mine with a Blue LED. Great instructions. Thanks for the info.....

 

hey, just curious, how many people had to switch the posts??? I am almost 100% positive i didnt write it backwards... Interesting. Does anyone know anything about the LED internal wiring?

Because of its composition, a diode will only allow current to flow in one direction.
If I remember correctly, an NP diode will only allow current to flow forward.
One side of the base of the diode should be notched, that's the negative pole of the diode, which should connect to the negative terminal of the battery.
If you look on a circuit board and see little black cylinders with silver stripes on one end, those are diodes too.
An LED converts almost all of its current to light, while a light bulb produces more heat than light, which is why an LED is brighter and lasts longer.
