Last sunday i went to Baghajatin at that shop but he was unable to give me any led as he himself could not buy it. So on monday i went straight to Chandni Chowk and bought 12 Blue Led from one shop but the shopkeeper was not at all ready to test them. Well, i went to another shop and asked for the same LED. The old man gave me a dozen and tested also. I also bought two multicolour LED. I requested the man to test the LED of previous shop and YES they are of bad quality glowing dimly. But i did not throw it away cause i want to make the experiment with them first.
On coming home I insert the +ve wire (indication is there)of multicolour LED(one piece only) straight in 12v(yellow wire) and the -ve wire in the black wire hole. Its ROCKING. Then i add the other one also. +ve wire of both added in 12v and the -ve wire of both in black hole. Its again ROCKING.
System shutdown LEDS apart.
Now i take out a single piece of blue led(shop A) and insert longer leg(+ve)straight into 5v (red) and shorter leg (-ve) into the black hole. It works. No resistance required. i repeat it with the LED of shop B. The shopkeeper says that the lLED are of 3v. But how come they withstand a 5v power source?

now tell me whther i will go for a parallel or series connection for BLUE LED only ? those multicolour i have decided where to fix.
is it a good idea if i use a thermocol platform and insert the LED in it and then go for a connection ?
