DIY Led Indicator Bulbs - xBhp.com : The Global Indian Biking Community

Hi,
I did some DIY LED Indicator lamps for activa. These may work with other bikes using the same kind of bulb holders & led flasher.

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.

Nice bro.Hows the intensity of light? Post some pics.

and what about the total cost?

Nice job. With SMD LEDs, you can pack more LEDs or compact the size of the entire package

Nice DIY Janesh..But still it will require the electronic flasher circuit..right?

Thanks deville, Yes we can pack more LEDs by using SMD type, but we need someone to do SMD type soldering, maybe in future

Yes prashant, we still need electronic flasher for these bulbs.

Aren't electronic flashers load driven ?

I'm having a 'four SMD type orange coloured bulb' with T10 holder.

Will the indicators work if i just fix the positive and negative from the existing indicator wiring correctly in my Pulsar 150 UG3?

I did not understand anything about the electronic flasher and all. Your setup of wiring another bulb for creating the load seems uncomplicated. Could you share some photos of the actual setup how you did it. I'll try to port the same thing to my P150. Or will the LED indicators work directly in mine?

Depends on how they are designed. And since electronic flashers are generally used to drive LED indicators they are not load driven. Even if they are, the load required to drive them is as low as the LED's would put.

guys!! a li'l suggestion.. wat about using LED strips around that traingluar shapr breadboard.. it would hold around 8-9 LED's atleast.Wud b sufficient enoghu @ night(Day as well :P). i just love those strips. and these strips use very less power (~0.5-1 W) in comparison to stock 35 W bulbs... i wish we cud have high intensity LED headlights as well;not costing a huge amount .
