in your security led pics it looks like you found some LED bulbs that are a direct replacement and have the right connector type to be used to replace several bulbs in the car... where did you get those? how much

 

sniper,

The LED was soldered on a tiny (1/4 inch sq.) PC board with two surface mounted resistors and one tiny transistor. Here what you will do:

1. Remove the LED and replace it with this one from Agilent,
part # HLMP-EG08-Y2000. I was able to get from Agilent as a free sample

2.

2. Remove one of the two resistors and put a jumper where you just removed it. You can solder a wire across it after you remove the resistor.

FOR EXTRA LED (used this LED from LEDtronics, Part # L206CR3K-5.4VF)
1. To install extra LED you need to drill a hole locate next to it.
2. Find a way to mount the resistor you just removed and the extra LED on a PCB. What I did is by cuting a 1/4 inch of PCB to mount the LED and resistor.
3. Now get your 12.3V power supply from the two wires that are connected to the first LED. Make sure which is "+" and "-".
