As Dr_D said, you can make one yourself even cheaper then Rs. 200 for a pair.
All you have to do is buy the LED from any electronics shops, the color and power depends on what you are looking for.
Add a resistor so that you can power it with a 12v car system, for example if the LED you choose is 2v and you want to power it with 12v, the formula to find the resistor you need is:
R=( Vs -Vl) / I
here,
Vs is the source that is 12v
Vl is the power of led thats is 2v
I is the current the led draws (normal led draws 0.020ma)
Therefore: 12 - 2 / 0.020=500K
Normally the the resistor should be attached to the cathode leg of the led but i think it works on both legs. The cathode leg is the short one out of the two normally.
Attach the resistor is series and plug it to your battery and your good to go : ).
remember, if you think you made a mistake in calculation of resistor needed, always use a resistor that is a bit higher in strength then needed. for example you calculated 220K so put 250K but not 210K.
I hope i made myself clear.
Thanks
