Pop bumper cap - blue transparent
Blue transparent plastic pop bumper cap for Williams/Bally and other 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.
