    Is it possible to have a 12v LED rope light hook up to an LED light organ in a car using the 12v car battery? I found something that is similar but works with 4 LEDs and i was wondering if you could hook up the rope light to it.

    Ok. Would it work with a 48" strip that contains 60 blue LEDs and operates on 290-400 mA @ 12Vdc?

    Hello,

    You could replace the transistors 2 4 and 6 by 2n2222 types.
    The 2n2222 can handle the current you require.

    Is it possible to have two of the LED rope lights hooked up to it?

    Hello,

    Then you will need a more powerfull transistor.
    Something like a darlington transistor like a TIP120, that can handle upto 4 A.
    Look afther cooling the transistor.

    The color organ circuit drives only a single LED on each of its driver circuirts. It will not drive a rope light that is a series string of LEDs.
    It can be modified so that each driver can drive its own rope light.

    The Hobbytron product does not have a schematic and the German site is asleep and does not open.
