Materials: Superflux red LED's (eBay 20 for $13.50 shipped), you need six for each light.
Prototype circuit board (I used some stuff from Radio Shack that I was given).
Your door light.

Start by removing the bulb from the light and cutting two strips of prototype board to fit into the light.

Then mount the LED's on the strips.


The LED's will come with resistors (you use these to limit the current to the LED's so they don't burn up!). The LED's mount Three to a board and use one resistor for each three LED's. The LED's are connected in series (anode to cathode or + to - if you like) and the resistor goes to the + side of the three LED's and the other end of the resistor connects to the positive contact of the door light.


The - side of the three LED's goes to the ground contact of the door light (use the end of the diode without the band).

Build the second strip and mount it as you see in the picture. The resistor ends going to the positive contact of the door light are soldered to the bulb contact as you see in the picture.



This DIY is aimed at those who have a basic understanding of LED's and how to wire them up for 12 volt operation. If you haven't played around with LED's jump right in and have fun, just be prepared to kill a few LED's as you learn.
