About the resistor and LED. Yes, its always suggested that they should go both hand in hand. Do not separate them and make any sin. Lol.
It does make you feel 'cool' spcially when you have people who are fascinated by the blue lighting. I plan on switching to white LEDs though in the long run. And yes, i would be wedding the resitor with the LEDs. Who am i t keep nature apart?

Well, this wont be a pioneering task. bugboy has already successfully done the same on his Ikon. I was also thinking in terms of blue lighting. More details here :

Also, the first gen Scorpio had an instrument cluster similar to that of the Ikon. Badboyscad has already done that as well.

Default Successful first phase of DIY

This evening i added 3 more blue LEDs in series with a 47 ohms resistor, and then connected this arrangement parallel to the series set up which i had created earlier. I also added a 47 ohms resistor to the previous arm of the parallel arrangement.

This makes it 6 LEDs providing good illumination within the car.

This marks the successful completition of the first phase of what i had planned in the DIY.

I did want to have white LEDs in the cabin, but dropped the idea for the time being as i dont have stock of the resistor with the required rating, and would need to buy them.

Benny,

Nice job. Just a wicked idea - - have 2 red, 2 blue, 2 yellow LEDS dance in sync to the music in the car.

Not a bad idea, though.

The background score could be Disco 82, perhaps?!

I want to sit in the front passenger seat while Benny drives - wearing sunglasses at night.

Cool stuff Benny - where's the party tonight?

Now i need to do this as well. I just need to buy the resistor. BTW did you solder it this time Benny? Or is it just the card board that you used just like the initial 3 LEDs?

You're welcome anytime, Hrishi. cheers:
The party's in the Ikon.. in the Ikon.

Nopes, no soldering this time as well. Put in holes in the cardboard and then inserted the LEDS and resistor in them, somewhat similar to how a breadboard would work.

All the connections between LEDs and resistor were done below, thereby preventing the arrangement from looking messy. I then used another small layer of cardboard below this (notice the staples on the cardboard) to prevent any of the connections from shorting with the positive terminal metallic strip of the cabin light.

Sanju, dont forget to put up the pics.

Didnt you see Hrishi's post above? Says he wants to be the one wearing the sunglasses.

Please dont do LED circuits without resistors because by getting the LEDs over nominal current you make them overheat and rob them their extraordinarily long lives. A 20mA LED working at 50mA will be giving out slightly below double its normal light emission (the overheating makes it far less efficient), but it will only live between 100 and 500 hours (4 to 20 days), contrary to its theoretical mean life of 50,000 hours (5.7years).

hmm now that explains a lot fo things that happened post my DIY ! thnx badboy for clearin that up !

@Benny...

Awesome job. I just loved.

I had been thinking about a similar stuff for my car. But I did not get an idea.

But now, it looks so easy.

What's the wattage on the LED's. 3.5V is the voltage but what is the current they should be getting.

The stock bulb is generally 12V/8W = 1.5A current. Based on that I plan to add the LED's solder all these on a small PCB.
