Check out tis sideswipe. I made a reflector beneath the clear plastic, to transmit the lights, so it lights up the whole head lights. It is easy to do, use some clear plastic (u can use the box of the toy or others if u stil wan to keep the box), fold it in shape and cut it, then find those shining wrapping paper or aluminium foil that ur mom used to cook. Glue it to the plastic and so on glue to the clear plastic headlights. Wiring blue led in his head, and the red tail lights. The tail lights is easy to be done because there is plenty of place to hide the resistor and led. Nth else more to say about it, jus feeling some difficulties to wiring his headlights, but finally overcome it. The blue lights come out from the robot's head. I like the effect, Like those I.C.E modification in the real car. If u dun like it u can simply cover it with black paint. As usual as u saw, tat is external power cord.
