    i have an power supply having 12vdc 6amp
    when i connect 4 leds in series they work fine
    and when i connect second 4leds (which is also in series) circuit in parallel
    with in 5 second the second circuit having 4leds blown away ,and first circuit remain working fine
    I THINK RESISTORS WAGAIRA LAGANY PARINGY MAY BE BUT KITNY OHM KA LAHGAON ,KAISY CALCULATE KARU

    yes go for LED strip for neat, easy and long life job. if you must use LEDs install 680 ohm resistor on each LED. 1K resistor as told by aliam_786 is also good as glow will be little less but life longer. using leds in series is not a good idea.

    auto decorator shops se LED strip 80 rs / foot bhi milti hai. aur i think 1 ft kafi hai apke kam ke liye. strip pe har teen LED ke baad do points hote hain connection ke liye jin pe wire solder kar di jati hai.

    Salam dear friend, i'm professional in this work,
    Listen, some times 4 led's did not work fine in series, make series of 2 led's, then install 380 ohms resistor in both series to negative (-) point and install 1amp diote on positive (+) point, but be carefull while installing diote, b cz diote have two sides, + ve and -ve, conect +ve side to +ve point of series, diote have white or silver mark on +ve side.
    Cheers!
