Pop Bumper cap - clear
Clear transparent pop bumper cap is used on many late model Williams and Bally pinball machine Pop Bumper assemblies.
Change pop bumper cap lamps to LEDs even if LEDs are not used 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.
