It is doable. The main problem would be in fixing the orange LEDs inside the backlight setup. Don't know if the backlight has extra space inside to fit the LEDs. So, that is what you should check out.

Bro, actually when I was researching on this.... I also came across the same consideration. The solution which I found over Internet was Dual Colored LED, which change their color based voltage passed. But over here in Gurgaon, it's really hard to find some actuall serious stuff

But anyways I'll keep my research on.... I'm very keen towards doing this!!

If you can replace the LEDs with dual coloured ones, it is possible. Anyways, if you are really interested, find the size of the Pulsar LED and order dual colored LEDs of the same size online. Also, they change their color based voltage passed and there are LEDs with two connections. Switching ON one connection lights up one colour, the other connection, the other colour. Here, no messing with voltage levels. Also, if you switch ON both connections, both colours will light up together combining to form a third colour.

Wow..... the second option sounds great!!

It would be very helpfull if you could help in out with -

1) How can I find out the size of LEDs used in the Back Light
2) From which website I can securely order the Dual Connection LEDs

Thanks in advance!!

@abhijeet: I'm interested modding my speedo the same you have... (in white)

Could you tell me if you put normal leds or got some special thing?? I've never opened the speedo so I dunno wat those bulbs look like... a pic of the leds would be of great help...

thanx

For the size of the LEDs used, the only way to know is to open the Pulsar backlight console and find out. Common sizes include 3,5,8 and 10mm. As I do not have access to a Pulsar LED backlight console, I am afraid I can not help there. The LEDs may even be fixed in such a way that it may not possible to replace the LEDs. So, the only way to know is to examine the LED backlight console.

Regarding websites, I am afraid I do not have much idea. I only know that dual coloured LEDs are available at Ritchie Street in Chennai and Lamington Road in Mumbai. Since, you are not from these places I suggested buying online. Maybe someone else can help you here.

A normal speedo does not contain LEDs. They use 3W bulbs. I have installed the LEDs. It has few normal 5mm white LEDs glued to the underside of the speedo dial.

Here is a pic of a LED -

The 5mm LED I have used is the one at the centre. The rightmost one is 3mm and the leftmost one is 8mm.

Thanks Bro.... I'll look out for the options

Ok I may come across as quite a dunce to post this question after 5pages of discussion. But I am planning to do the same LED fittings on my bike( HH Hunk). So if there was a step by step guide to do it( If somebody takes the pain to write that) it would be very helpful for me.

I don't have a Hunk. So, sorry, not possible for me to write step by step guide. But, the electrical circuit should be similar. Only the placement of LEDs may differ. Read my first post clearly. Most of the steps are similar.
