A first neon light bulb or fixed pointer is mounted on a point of the periphery of the disc and a second neon light bulb is mounted in a fixed position adjacent the periphery of the disc. Both light bulbs are joined to a flexible lead wire connectable to a spark plug lead. The socket of the flexible shaft is rotatably adjustable to the shaft with a pointer on the shaft, adjacent the socket, aligned with the relative position of the first light bulb on the disc.
