    Is it correct?

    I know, I mean I guess, it's not correct because of the polarity. but let's say the polarity is correct, is my led correct???

    Hello,

    The schematic is correct.
    Only all details are missing.
    What is the battery voltage?
    What is the voltage drop of each led?
    What current should be used for the leds?

    Everything appears to be correct so far.

    The battery is drawn with the positive terminal towards the top of the schematic, which is the way it should be.

    The resistors will limit the current through each series LED string, which is how it should be.

    The LEDs are shown with the anodes on top and the cathodes towards the bottom, as they should be.

    Basically, all you need now is the battery voltage, the LED typical Vf (forward voltage) at a given current, and then calculate the resistors.
    It would also be good to include a fuse and a power switch.
