I added LEDs into the clowns eyes to make him seem more creepy. I used some LEDs bought from hobby partz that will take 5volt input to make them glow. Remember how the sabertooth motor controllers have built in 5volt regulators, well simply plug the LEDs into your RC receiver and they will turn on when you turn on the main power switch of the powerwheels. I drilled holes through they clowns eyes and fished the wires through and all the way back down the clowns torso and into the receiver. I used more foam to cut out some scary eyes (my art wife had to help me there) and put LEDs in them as well.
