    I'm trying to take a motorised ghost that runs on 3 AAA batteries. I would like to put two red flashing led's as eyes to flash opposite of one another and run off a 9volt battery with an on/off switch, ....please help! ....thanks!

    You can buy a kit.
    This has two red LEDs, a speaker and a motor. A microphone picks up noise and when a threshold is reached, the LEDs will blink, the speaker will emit one of a few different ghostly sounds and the motor will make the ghost rattle.
