This really is a fantastic lighted mod , the rocket light flashes every time the Power Payoff light flashes, which is many times during the game, including every time the rocket ship ball launches. The rocketship light is a high intensity LED which reflects off the "blast" mounted underneath. There are no modifications to the machine, the ship is mounted with one of the existing screws at the ball rocket laucher and two alligator clips go on to the Power Payoff light and the wiring is tie-wrapped to the ball rail, a 5 minute job, installation instructions are included.
