Great post, easy fix. It cost me $2.14 with tax to fix. Mke sure you get a 12v LED. Tools needed, solder iron, solder, solder sucker. I could not find my solder sucker so used a air hose and blew the solder out from underneath the weld.

1999 Ranger - didn't have to pull the radio but it took a bit of doing to get the switch cover off. Radio Shack's LED selection was pretty thin for 12V, finally found a red one. I also figured out a way to make sure I have the LED in correctly. Plug the module back in, and put the LED wires on top of/ in contact with the old ones. Light on for lamp test when you turn on the ignition = correct, otherwise ignition off, reverse, try again.

Enjoying that cold frosty beer now as directed by the procedure...

 

I wanted to add my 2 cents to this great thread that saved me a huge amount of money. On all lights like this the Longer pin is always Positive.

Great thread, worked great. This sight has been good to me & my new/used truck!

 

This is a great thread. I picked up a green led since the interior ligjting is green and a resistor,(Radio shack didn't have a 12 volt green led). Found out I am not the best at soldering on a circuit board, but with a little patience i got it done. Thanks again!
