Firstly, you will need indicator bulbs, as many as u plan to convert to LED. Now we need to do what we usually dont do with bulbs, smash the bulbs.
Please use caution to break them as small splinters may cut your hand.
Use a cloth or cotton cloth to wrap the bulbs and break them.

Once the glass is removed, you need to clean out the holder which has some ceramic material inside.

Secondly, cut out 3 pieces or PCB (use general purpose board). I used the size of 12mm x 35mm pieces as the bulb holder is 14mm in dia, so 3 of the pcb will fit in there in a triangular manner.

LEDs: I used dome type leds which have a larger viewing angle, so light spread is more than typical leds.
Solder 3 leds in series and one resistor of 120ohms ¼watts. Wire the resistors from all the 3 pcbs together and connect it to center of the bulb holder. (You need to use solder iron to make a hole through the center contact).
For the grounding you need to connect the top of the LEDs (negative terminals) and wire it down to the outer shell of the bulb holder.

You need to apply double side tape or any insulating tape at the back of the pcb so the led contacts do not touch the adjoining sides.

Once the pcbs are ready, slide them into the holder, with the +ve wire going through the centre of the holder, and the ground to the outer shell of the holder.

Empty Bulb Shell


3 PCBs cut out in 12mm x 35mm


The 3 pieces glued so it becomes easy to insert them together in the shell


LEDS** mounted on the PCB (see description of LEDs below)


Completed LED Bulb



** The LEDs i used are called 5mm superflux LEDs or Dome LEDs. Attached is datasheet for the same.
(PS These are available with Asian Electronics in Mumbai) PM me if u need contact details.
