MACHINE (Williams) Pop bumper cap set
Set of 3 new red pop bumper caps for Williams THE MACHINE BRIDE OF PINBOT pinball machines.
Change pop bumper cap lamps to LEDs even if you don't chose to use LEDs elsewhere in your machine. This will prevent the pop bumper caps from incandescent lamp burn as the lamps age and overheat. A warm white LED (see related items below) is a perfect substitute for any pop bumper incandescent lamp.
