MARDI GRAS (Williams) Pop bumper cap set (4)
1962 Williams MARDI GRAS pinball machine 3 piece pop bumper cap set.
Change pop bumper cap lamps to LEDs even if you don't choose 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.
