1. How did you connect LEDs in the instrument panel ?
2. Also, if I choose white LEDs do I need to use the same resistor value?
3. Sand Papered - u mean u rubbed the LED using sand paper ? How does this help? Cant I use LED without Sand Paper ?

1.

3LEDs' connected in series were placed in the holes where the stock bulb was present, I used some sticky tape to keep the LEDs in place
And the terminals from the LEDs were connected to the socket/plug on either side which used to carry current to power up the stock blubs.

2. For correct value of resistor required check this:
Current limiting Resistor calculator for leds

3. As told as badboyscad

@ tanwaramit , this link should help you with ideal diode specifications, a White LED will have a Vf of 3 to 3.5v (typically 3.5v ) If should be 25-30mA .
led specs - Light Emitting Diodes (LEDs)
calculator - LED series parallel array wizard

Really awesome work akshay_b. The blue illumination looks great.

A few questions for you buddy -
How much did the LED's cost?
Where did you purchase them?
Any specific brand you picked up?

Thanks diiesoline

2 bucks a peice
In a general electronic/electrical store
No buddy the usual transparent LEDs' will do just great

Hi Akshay,

Thanks for the link, however, I am confused with the following two.

1. Source Voltage -- How much it would be for Santro Xing ?
2. LED Voltage -- Assuming it to be 4V (am I correct on this assumption (for white LEDs?)
3. Current -- 25 - 30 mA (as told by Abhay)

Please help on the numbers, couldnt do last weekend as was out of town for 3 days chutti, will do this weekend...

Looking for white color as it looks great on Honda Accord.

Thanks in advance.

1. Source voltage will be 12v inside the instrument cluster.
2. LED voltage- I'd prefer 3.5v for white leds. (U wouldn't want the LEDs to heat up)
3.Current- 20~23mA

To-buy list:

6 White leds(3 on each side), buy 2 more in case if u break the terminals while connecting
two 82 Ohm resistors
A meter of insulated thin wire.
Insulation tape
Scissors
sand paper

Thanks a ton, will try it out this weekend n will upload pics

Please somebody tell me the type of bulb and if possible put some pics also.

Good DIY let me try the same on the Zen, any idea why the LEDs are sandpapered?

You can use the regular transparent LEDs that you get in a neighborhood electric shop.

Or else you can try this

Plug&Play.

So that the focused light beam doesn't fall only on one part.
Try the link that i mentioned.
