    Hello guys i am doing a small LED blink stuff.please view the attachment first.

    I am sure you know these kind of led blinks.I am not sure on what basics this leds blink whether it is voltage or power.I have made a small circuit which does this (it ON's the leds depending on voltage).i have attached the image of the circuit.

    by the way the supply is from a car battery and for the comparator i am gonna use a 5v Regulator and output of comparator is connected to a LED

    please help me i am not sure if this works.
    Thanks!

    That is not going to work. It may distort the amp or even kill it. The circuit will not work.

    Is this supposed to go in a car?
