JOLLY JOKERS (Williams) Pop bumper cap set (3)

1962 Williams JOLLY JOKERS pinball machine 3 piece pop bumper cap set.

Installation Tip:

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.
